Description:FIELD
The present disclosure generally relates to the field of utility distribution networks. Particularly, the present disclosure relates to a system for generating a single line diagram (SLD) of a utility distribution network and a method thereof.
BACKGROUND
The background information herein below relates to the present disclosure but is not necessarily prior art.
Traditionally, utility networks rely on Single Line Diagrams (SLDs) to visualize and manage operational activities. These diagrams represent the network and its field assets using lines, texts, and symbols, providing insights into the operational status of network elements. However, SLDs are typically created and managed by different authorities using various formats such as Excel, PDFs, Word documents, or AutoCAD, leading to inconsistency and challenges in maintaining up-to-date SLDs across the entire utility network remains a primary challenge.
Supervisory Control and Data Acquisition (SCADA) systems are commonly used to automate asset operations, storing field asset information hierarchically similar to SLDs. This highlights the importance of accurate and unified diagrams in utility management. While Asset Management Systems like SAP store network asset data, they often lack essential connectivity information, making it impractical to derive a compatible data format. Further, Geographical Information Systems (GIS) hold extensive data including route information, location data, operational status, and connectivity details, making them promising for operational purposes. However, integrating GIS data with other systems is challenging. This gap often necessitates manual processes or workarounds for SLD generation and maintenance, which are time-consuming and error-prone.
There is, therefore, felt a need to develop a system and a method for generating a single line diagram of a utility distribution network to alleviate the aforementioned disadvantages.

Purpose of Key: To define size or bounds (length and width)of drawing in drafting software based on number of LT Switchgear connected with particular transformer.
The plurality of keys is defined by abbreviations corresponding to the identified plurality of network-assets of the electrical distribution network. The keys can be determined as follows:
Asset classification Assets detail Abbreviation
Source Structure Substation SS
Source Element Transformer DT
Controlling Structure LT Switchgear LTP/FP/MNP/BR
Controlling elements Circuit Breaker/Fuse/DLink/Isolator CB/F/L/Isolator
connector Element Cable/Busbar Cond/BB
End Points Consumer Meter/Fire Panel, Supply point SP/FR
Measuring element Primary Meter PM
Further, the plurality of keys is assigned with a corresponding plurality of suffixes for differentiating the purpose of each of the keys. For instance, when dealing with LT Switchgear assets, the suffix "Details" is associated with them to signify the provision of detailed information about the asset. Additionally, in cases where the LT Switchgear contains arrangements of fuses, the suffix "Arrange" has been identified to denote this specific aspect of the asset. Likewise, the following suffixes can be used to denote the purpose of the keys for a particular network asset of the electrical distribution network.
Suffix details in the Key Description
Template data Define the overall Elements in the Network
Sequence Structure Sequence in the network
Details Detail information of the network element
Load Connected End points details with controlling elements
NetConnect source and destination point pair information
NOP Normal open point details in the network
nconnect network branch element detail
Arrange sequence for controlling elements inside controlling structure
Table Network detail information to generate information in Tabular format
The plurality of key-values also includes at least one separator for distinguishing values between to network-assets or to define an attribute value to a network-assets. For instance, in a key that represents a network asset, separators might be employed to distinguish different components of that asset, such as its location, operational status, or related parameters. Additionally, when specifying attribute values for a given network-asset, separators help divide individual attributes, making it easier to interpret and utilize the data. This design choice ensures that each piece of data-frame is clearly defined and can be efficiently processed and managed within the system.
Following is the example of separators that can be used:
Separator Description
$ To differentiate between elements in value field
# To differentiate different information of a particular asset in value field
@ To differentiate between different attributes of a particular information in value field
