BACKGROUND
[2] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[3] Auditing requires collecting various key data for analysis and decision making to affect changes in existing system for better performance in terms of process optimization, efficiency enhancement and energy conservation. Auditing is generally done by an expert or a team of experts by visiting the facility to be audited. A considerable amount of time is required however to collect the data and reach a certain result. Based on the data collected, a detailed analysis is done and the analysis is then converted into an audit report. The audit report also includes an approximate budget needed to implement auditing measures imposed. And other cost inducing factor is that auditors charge fee for conducting the audit and customer also need to take care of the boarding and lodging expenses of the auditors. For large scale industries, it is possible to bear the expenses but small scale industries face difficulties in meeting those expenses. Due to this small scale industries are losing the growth path in terms of implementing the key technological changes available in the market and which has been well adopted by their counterparts in large scale industries. As a result goals of energy conservation are lagging behind and requires an urgent intervention by bringing these small scale industries at par with the market standards.
[4] There are products in the market that use different motor starters compared to the conventional motor starters. There are many other similar solutions available in the market but due to lack of awareness and skilled workers at small scale industries, these products have not been implemented in small scale industries. Moreover, due to high cost involved in these products, providers neglect the small scale industries. And as a result, small scale industries too do not feel the need to adopt to new technologies.
[5] There is, therefore, a requirement in the art for a cost effective easy device to enable analysis of power consumption by remote access without the requirement of visits by auditing experts.

[44] FIG. 1 illustrates an exemplary network architecture of an auditing system 100 in accordance with an embodiment of the present disclosure.
[45] As illustrated in FIG. 1, according to an aspect of the present disclosure an auditing system 100 (also referred to as the system 100, hereinafter) can provide auditing of power consumption attributes by signal processing techniques. As illustrated, an auditing device 106 can be operatively coupled to a control unit 102 which can be further communicatively coupled with one or more remote computing devices 108 (individually referred to as the remote computing device 108 and collectively referred to as the remote computing device 108 hereinafter) through a network 104. In an embodiment, the system 100 can be implemented using any or a combination of hardware components and software components such as a cloud, a server, a computing device, a network device, and the like. Further, the auditing device 106 can interact with remote computing devices 108 through a website or an application that can reside in the auditing device 106 and the computing device 108. In an implementation, the system 100 can be accessed by website or application that can be configured with any operating system, including but not limited to, AndroidTM, iOSTM, Kai-OSTM and the like. Examples of the computing devices 108 can include, but are not limited to, a computing device 108 associated with industry based assets, a smart phone, a portable computer, a personal digital assistant, and the like.
[46] Further, the network 104 can be a wireless network, a wired network, a cloud or a combination thereof that can be implemented as one of the different types of networks, such as Intranet, BLUETOOTH, cloud, Local Area Network (LAN), Wide Area Network (WAN), Internet, and the like. Further, the network 104 can either be a dedicated network or a shared network. The shared network can represent an association of the different types of networks that can use variety of protocols, for example, Hypertext Transfer Protocol (HTTP), Transmission Control Protocol/Internet Protocol (TCP/IP), Wireless Application Protocol (WAP), and the like.
[47] In an aspect, the system 100 can receive from the auditing device 106, a first set of attributes pertaining to electrical machines of a facility. In an embodiment, the control unit 102 can be configured to receive electrical signals from the auditing device 106 to further process the attributes to determine the power consumption by the electrical machine or the components thereof. For example, the electrical parameters can be related to energy and power consumption of electrical machines in any small scale and large scale industries.
[48] In an aspect, the control unit 102 of the system 100 can be configured to receive, from the auditing device 106, a set of signals pertaining to the plurality of electrical parameters. For example, the electrical parameters can be any or a combination of resistance, capacitance, inductance, current, load power, and the torque value. The control unit 102 can be then configured to extract from the received set of signals, attributes pertaining to power consumption of the machine. The control unit 102 can then identify, from extracted attributes, one or more components of the machine that consume more power than a preset threshold power value. The control unit 102 can be then configured to generate an alert signal pertaining to the excess consumption of power by the one or more components of the machine, wherein, the alert signal can be indicative of any critical power consumption value based on the preset threshold value and preset configuration rules pertaining to the machine. The control unit 102 can be further configured to determine based on the identified one or more components that consume excess power, power saving measures for the one or more components, wherein the power saving measures are indicative of modifications to the electrical machine such that, on implementation of the power saving measures, the one or more components of the electrical machine consumes power within the preset threshold power value; and communicate, to a r computing system, though a communication network, the set of signals pertaining to the electrical parameters, the power consumption determined from the received signals, information about the one or more components of the machine that consume power more than the preset threshold value and the alert signal generated.
[49] In yet another exemplary embodiment, a user can access the auditing information through the remote computing device 108 connected with the network 104. The user can further gain access to the control of the auditing device 106 through the remote computing device 108, wherein the computing device 108 can be configured to control the auditing device 106 through the network 104. In an embodiment, the computing device 108 can be situated in the vicinity of the auditing device 106 or at a remote location. For example, the user can log in to the computing device 108 that can be in the vicinity of the auditing device or in a remote location through network 104 to access the details of the auditing device 106. The user can also recommend specific settings required for power saving. The user can further generate his own test values to determine working of the auditing device 106. Thus, the user can remotely observe the auditing information, generate his own test conditions and provide required measures without the need of being physically present in the facility.
[50] FIG. 2 illustrates an exemplary architecture of a processor coupled with the auditing device (106) in accordance with an embodiment of the present disclosure.
[51] As illustrated, the control unit 102 can include one or more processor(s) 202. The one or more processor(s) 202 can be implemented as one or more microprocessors, microcomputers, microcontrollers, digital signal processors, central processing units, logic circuitries, and/or any devices that manipulate data based on operational instructions. Among other capabilities, the one or more processor(s) 202 are configured to fetch and execute computer-readable instructions stored in a memory 204 of the control unit 102. The memory 204 can store one or more computer-readable instructions or routines, which may be fetched and executed to create or share the data units over a network service. The memory 204 can include any non-transitory storage device including, for example, volatile memory such as RAM, or non-volatile memory such as EPROM, flash memory, and the like.
[52] The control unit 102 can also include an interface(s) 206. The interface(s) 206 may include a variety of interfaces, for example, interfaces for data input and output devices, referred to as I/O devices, storage devices, transducers, actuators, and the like. The interface(s) 206 can facilitate communication of the control unit 102 with various devices coupled to the control unit 102. The interface(s) 206 can also provide a communication pathway for one or more components of the control unit 102. Examples of such components include, but are not limited to, processing units 208 and database 210.Said interfaces can allow non-technical users to access and manage data stored in database 210. For example, said interface can enable the user to access power consumption of an electrical machine and can enable the user to observe the results of the values pertaining to the power consumption of the electrical machines of a facility. In another exemplary embodiment, a preset threshold power value can be stored in said database 210. Herein, said database 210, can be configured and developed through the interface 206 that can provide key information pertaining to power consumption of electrical machines of a facility. Thus, an advantage of the proposed system can be to for easily making auditing changes through a remote computing system.
[53] The processing units 208 can be implemented as a combination of hardware and programming (for example, programmable instructions) to implement one or more functionalities of the processing units 208. The database 210 can include data that is either stored or generated because of functionalities implemented by any of the components of the processing units 208.
[54] In an example, the processing units 208 can include a scanning unit 212, an analysing unit 214, an alert generation unit 216, and other unit(s) 218. The other unit(s) 218 can implement functionalities that supplement applications or functions performed by the control unit 102 or the processing units 208.
[55] In an embodiment, the scanning unit 212 of the control unit 102 can include processing units 218 that are responsible for extracting electrical parameters from an electrical machine upon receiving acknowledgement from one or more processor(s) 202. The electrical parameters can include any or a combination of current flow, voltage drop, resistance value, capacitance value, inductance value, impedance value and load torque generated. The scanning unit 212 can be coupled to a screening device that can include a plurality of test motors and a plurality of test motor controllers. The test motors can be connected in any or a combination of direct online (referred to as DOL hereinafter), star-delta starting, soft starting and variable frequency drive (referred to as VFD hereinafter). For example, in an embodiment, DOL starting can be simply switching the motor on in one operation, with a direct connection from the power source. It can be generally used for smaller loads, as the starting current can be up to ten times the normal running current of the motor. A contactor can be generally used to switch power, and often any or a combination of thermal and electronic overload relay can be provided for motor protection.
[56] In another exemplary embodiment, the plurality of motors can be started using star-delta method, wherein, the plurality of motor scan be first connected in ‘star’ configuration, which can allow the plurality of motors to gather speed without drawing excessive current. Once the plurality of motors catches up to speed (or a preset time is elapsed), the plurality of motors can be then connected in the normal ‘delta’ configuration. This method can reduce the starting current demand by 30%, but can be only suited to applications where the plurality of motors are without load.
[57] In another exemplary embodiment, the plurality of motors can be provided with a soft starter that can be an electronic device which can regulate the voltage flowing to the plurality of motors at startup. By slowly ramping up the supply voltage to the plurality of motors, a smooth start without excessive current flow can be achieved.
[58] In yet another exemplary embodiment, the plurality of motors can be provided with a VFD, wherein the VFD can be an electronic device which can allow complete control of the motor speed including starting and stopping. It can operate by changing the frequency of the power supplied to the plurality of motors. A VFD can be extremely versatile and often can be used in process applications where a constant pressure or flow needs to be maintained. In addition, because the plurality of motors can be run at a slower speed and thereby lead to lesser use of power and energy, use of a VFD can facilitate significant power savings.
[59] For example, in an embodiment, any or a combination of DOL and Star-Delta energy consumption parameter can be logged as per schedule selected by the user. Same reading can be logged for running the scanning unit 212 coupled to the screening device having VFD starter at different frequencies as per the electrical machine requirements and specifications. The two sets of data can be then communicated to the analysing unit 214 to measure the same. For example, the scanning unit 212 can be configured to run the test motors at different frequencies and identify power consumption based on the type of load. The load can be any or a combination of variable torque load and constant torque load. Thus, due to the presence of such embodiments, enabling power saving measures, smooth motor start-stop, longer life of motors and automation can be easily achieved which can be an added advantage.
[60] In an embodiment, the analysing unit 214 of the control unit 102 can be configured to sense the electrical parameters received from the scanning unit 212 to calculate power consumed by the electrical machines and the components thereof and store the values in the database 210 for future considerations. For example, power of the machine can be calculated by any or a combination of dividing voltage drop to the power two by resistance or impedance value and current to the power two by resistance or impedance.
[61] In an exemplary embodiment, the control unit 102 can provide for the analysing unit 214 to determine excess power by comparing the power determined with a preset threshold power value stored in the database 210.In an exemplary embodiment, the preset threshold power value can be configured based on a first visit of expert team to set critical attributes for target applications.
