FIELD OF THE INVENTION

The present disclosure generally relates to an automatic layout generation of gas-insulated metal-enclosed switchgear bays with gas insulated bus ducts for substation applications. The invention also relates to formation of GIS bays with the bus duct based on the requirements of single line diagram (SLD). The present invention further relates to optimize the number of the branches of bus ducts, height of the bus-ducts and distance between support structures of bus duct etc. based on input parameters like building dimensions, yard dimensions, etc.
BACKGROUND OF THE INVENTION
Background description includes information that may be useful in understanding the present subject matter. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed subject matter, or that any publication specifically or implicitly referenced is prior art.
Gas insulated substation modules and configurations thereof for the field of electrical power generation and distribution and more particularly to optimization of gas insulated substation bays along with gas insulated bus ducts based on customer requirements. Gas Insulated substation equipment is generally categorized by their installation location, the bay configuration with components e.g. circuit breaker, dis-connectors, maintenance earth switch, fast acting earth switch, current transformer, potential transformer, surge arrester, SF6 gas to air bushing, gas-to-cable terminations etc. The GIS design methodology employs gas insulated bays, Bus bars, bus duct and support structures for all three phase modules. Gas insulated substations are made with various configurations / schemes like the single bus bar arrangement, Double bus bar arrangement, Bus coupling arrangement, 1 and ½ circuit breaker arrangement, Double bus bar with transfer bus, Double bus bar arrangement with bypass etc. During tendering any particular requirement, cost of all the components of customer requirement to be considered for the estimation of project cost.

There exist gas-insulated switchgear (GIS) assemblies can include a plurality of switches, which are electrically connected to one another via so-called bus bars for transmission of electrical power. Both single-phase-encapsulated and polyphase-encapsulated busbars are known. A single-phase busbar generally means a primary conductor which is arranged in its own encapsulation, in the form of a metal-encapsulated housing, by means of an insulation gas. In contrast to single-phase-encapsulated bus bars, in the case of polyphase—for example, three-phase— encapsulated bus bars, the primary conductors of different electrical phases are arranged jointly in a single metal-encapsulated housing.
In some cases of existing conversion, there occurs lot of difficulties occur while converting customer requirements in to manufacturing inputs. As per conventional practice, manual submission of generic parametrical 3D models and associated parametric 2D drawings, bill of materials (BOMs) etc. at the time of tendering takes two to three weeks and further accuracy of these estimations is limited. The process of generation of these documents has to be repeated as part of submission of post order to-be- approved documents.
Existing prior arts such as CN103633567A, discloses about the circuit layout structure of a GIS (gas-insulated metal-enclosed switchgear) power distribution device is dependent on adjacent circuit breakers at corresponding positions and between adjacent complete strings are connected with a main bus through the same branch. For a GIS power distribution device of an ultra-high voltage transformer substation, which comprises multiple complete strings in linear arrangement, the number of the branch buses and the length of the main bus which can be saved by the circuit layout structure provided by the invention are quite considerable, so that the floor area and the equipment cost of the GIS power distribution device are reduced. The previous developed designs are mostly considered only for Gas Insulated bay development and relation and dependency of the bay formation on the position of the circuit breaker. Similarly prior arts such as CN203607687U describe about gas-insulated switchgear and its configuration and development. However, the prior art method does not give any consideration

to the design of the multiple full bay modules and specifically the design of the gas insulated bus-duct module based on the space requirement at site and the defined single line diagram/layout by the customer. Further, the prior art does not consider the aspect of optimization of different possible gas insulated substation layouts in view of building dimensions, yard dimensions, project cost etc.
Thus, there remains a need for method and system for single line diagram based automatic layout plan generation for gas insulated substation and optimizing number of the branches of bus ducts, height of the bus-ducts and distance between support structures of bus duct etc. based on input parameters. Also, there is need for system and method for gas insulated substation comprising multiple bays and bus ducts of different lengths in variety of configurations depending on yard dimensions specified by utility.

FIG. 5 shows a generated model is a gas insulated switchgear 500 as per SLD1 arrangement according to an embodiment of the invention. In a preferred embodiment a double bus bar arrangement as shown in FIG.5, includes the

combination of a gas circuit breaker 01, a current transformer 02, a maintenance earthing switch 03, a fast acting earthing switch 04, a disconnector switch 05 etc. to satisfy the single line diagram requirement. As per single line diagram requirement per phase, to satisfy the condition, at least one of two disconnector switch 05, one maintenance earthing switch 03 towards bus bar side of the gas circuit breaker 01, Other side of it is connected to the maintenance earthing switch 03 through one current transformer 02, then feeder side disconnector 05 and one fast acting earthing switch 04 is connected.
In one embodiment the gas insulated switchgear bay 500 comprises of the gas circuit breaker 01, the current transformer 02, the maintenance earthing switch 03, the fast acting earthing switch 04, the disconnector switch 05, the expansion joint 06, a support structure for gas circuit breaker 07, a four-way connector / module 08a, a T-connector / module 08b, a gas insulated bus duct 09 and a gas-to-air bushing 10. In a preferred embodiment the design of gas insulated switchgear bay has fixed dimensions of bay width, height of the disconnector switches from ground and height of feeder side bus duct 09 etc. The bus ducts are supported with suitable structures at an appropriate distance 11. In one embodiment, the single line diagram called super SLD 202 is developed and certain modification are made to generate following types of configurations:
• Double bus bar arrangement (SLD1a) and Single bus bar arrangement (SLD1b)
• Bus coupling arrangement (SLD2)
• 1 and ½ circuit breaker arrangement (SLD3)
• Double bus bar with transfer bus (SLD4)
• Double bus bar arrangement with bypass (SLD5)
In one embodiment, a gas-to-cable termination or SF6 gas-to-air bushing 10 is used to connect the gas insulated switchgear 500 to the transmission lines or reactors or power transformers. The connection between GIS main bay 12 and the SF6 gas-to-air bushing 10 is extended with the help of the gas insulated bus ducts 09. The gas insulated bus duct 09 in the substation is used for connection between incomer / feeders with the actual substation equipment like shunt reactors, transformers, incoming lines and feeders etc. The bus duct design is constrained

with various factors like space, height, distribution point (i.e.) incomer/feeder point distance/location from the substation equipment. Parameterization of Bus duct for all three phases i.e. R, Y, B is done which caters to various lengths and angles based on the incomer/feeder point location. Further, using the system 200 estimate gas insulated bus duct unit length and non-standard bus duct lengths. Using the system 200, all configurations of bus duct could be measured. In a preferred example the standard length of the one bus duct unit is considered and based on the available space between incomer/feeder point location, the quantity of standard units and non-standard units are quantified. Using the system 200, the rules have been standardized/simplified and made as follows:
For a given required input length, Ra of the Bus duct, and with standard bus duct length x,
1) No of Standard Bus duct = (Ra- 600-2*46)/(x+46)
2) Remainder length = Mod ((Ra-600-2*46)/(x+46))
Where “600” is the standard expansion joint length used in this case which enables you to do adjustments to match the exact length at site erections. And “46” is the insulator length which is being used in between bus duct conductors. In one embodiment,
Case 1:
If, Remainder length <1200 say, a straight connector bus duct would likely come and if remainder length>1200, say a conical connector bus duct will be shorter than the standard bus duct length.
Case 2:
If it is more than Standard bus duct length, i.e. x, then one non-standard straight
bus duct 09A or one nonstandard conical connector bus duct 09A could be used
based on calculations.
In one embodiment suppression logics for conical and straight bus duct has also
been implemented by (if –logics) statement to choose which type of connector to
be used at the respective places and based on calculations for a given input length,
Ra.

In one embodiment length and locations of each connector i.e. bus ducts which includes (Standard conical bus duct, non-standard Conical or Straight bus duct) is calculated automatically from the in-built rules which has been built in the system 200.
In one embodiment in the system 200, the rules are calculated based on user input, sends the required parameters to models to update automatically and locates each components at its place and also suppression/ un-suppression of components whichever necessary are generated automatically for a given layout drawing.
FIG. 6 shows a system for a different bus duct configurations 600 generated according to an embodiment of the present invention. Various support Structures 07, 11 are positioned in supporting modules of GIS bay 12 and bus ducts in the substation. The support structures 07, 11 have been parameterized to locate with varying lengths and height of bay modules and bus ducts. The system 200 further comprises a graphic user interface with an input screen. An input screen for bus duct details is displayed. As displayed in the input screen, the user input the values of phase distance and dimension details of the available space and the design is be automatically generated as shown in FIG 6. The support structure 07, 11 assembly is parameterized in such a way that the base width and length, if and when changed, could ensure the individual structure stiffeners align and extend themselves to match the end structure as required. Also, the number of stiffeners could be changed based on the user requirement.
In one embodiment in preferred one side, the ladder arrangement stiffeners are also parameterized to change with respect to the structure height. Using the system 200, if the structure assembly is put under different load conditions during analysis and an optimized solution of height, width, length and number of stiffeners is obtained, this assembly could be easily modified through the parameters to obtain the end result. Room layout/dimensions are also parameterized to suit customer requirements, which help us to place the GIS at a particular location in the given room and vice versa.
