[0058] See also Figure 1 , Figure 1 The present invention provides a flowchart of a method for determining the power loss of a substation according to an embodiment of the present invention. The method for determining the power loss of a substation may include S101 to S107, which are described in detail as follows:

[0059] In S101, the rated power loss corresponding to each primary device in the substation, as well as the actual transmission capacity and the rated transmission capacity of the substation are obtained.

[0060] In the embodiment of the present application, when it is necessary to determine the power loss of the substation, the electronic device can first obtain the rated power loss corresponding to each primary device in the substation, as well as the actual transmission capacity and rated transmission capacity of the substation. The rated power loss may include the rated constant power loss and the rated variable power loss, that is, the electronic device can obtain the rated constant power loss and the rated variable power loss corresponding to each primary device in the substation.

[0061] In practical applications, the rated power loss corresponding to each primary equipment in the substation, as well as the actual transmission capacity and rated transmission capacity of the substation can be obtained from the nameplate of the power equipment in the substation or the on-site operation data of the substation. Therefore, it is relatively easy to obtain the rated power loss corresponding to each primary equipment in the substation, as well as the actual transmission capacity and rated transmission capacity of the substation.

[0062] Exemplarily, the user can input the rated power loss corresponding to each primary device in the substation, as well as the actual transmission capacity and rated transmission capacity of the substation into an electronic device, so that the electronic device can obtain the rated power loss corresponding to each primary device in the substation, as well as the actual transmission capacity and rated transmission capacity of the substation.

[0063] In S102, for each transformer device in each primary device, the sum of the first rated constant power loss and the sum of the first rated variable power loss of each transformer device are determined according to the rated power loss corresponding to each transformer device.

[0064] In an embodiment of the present application, after obtaining the rated power loss corresponding to each primary device in the substation, as well as the actual transmission capacity and rated transmission capacity of the substation, the electronic device can first classify and integrate each primary device, thereby classifying and integrating each primary device into a number of transformer devices, a number of parallel capacitor devices, a number of parallel reactor devices, a number of busbar devices and a number of switch devices.

[0065] Afterwards, the electronic device can, for each transformer device, determine the result of adding the rated constant power loss corresponding to each transformer device as the sum of the first rated constant power loss based on the rated power loss (including rated constant power loss and rated variable power loss) corresponding to each transformer device, and determine the result of adding the rated variable power loss corresponding to each transformer device as the sum of the first rated variable power loss.

[0068] In S104, for each shunt reactor device in each primary device, the sum of the third rated constant power losses of each shunt reactor device is determined according to the rated power losses corresponding to each shunt reactor device.

[0069] In an embodiment of the present application, after classifying and integrating each primary device into a number of voltage devices, a number of parallel capacitor devices, a number of parallel reactor devices, a number of bus devices and a number of switch devices, the electronic device can, for each parallel reactor device, according to the rated power loss (only including the rated constant power loss) corresponding to each parallel reactor device, add up the rated constant power loss corresponding to each parallel reactor device and determine the result as the sum of the third rated constant power loss.

[0070] In S105, for each bus device in each primary device, the sum of the third rated variable power loss of each bus device is determined according to the rated power loss corresponding to each bus device.

[0071] In an embodiment of the present application, after classifying and integrating each primary device into a number of voltage devices, a number of parallel capacitor devices, a number of parallel reactor devices, a number of bus devices and a number of switch devices, the electronic device can, for each bus device, according to the rated power loss (only including the rated variable power loss) corresponding to each bus device, add the rated variable power loss corresponding to each bus device and determine the result as the sum of the third rated variable power loss.

[0072] In S106 , for each switch device in each primary device, the sum of the fourth rated constant power loss and the sum of the fourth rated variable power loss of each switch device are determined according to the rated power loss corresponding to each switch device.

[0073] In an embodiment of the present application, after classifying and integrating each primary device into a number of voltage devices, a number of parallel capacitor devices, a number of parallel reactor devices, a number of bus devices and a number of switch devices, the electronic device can, for each switch device, according to the rated power loss (including rated constant power loss and rated variable power loss) corresponding to each switch device, determine the result obtained by adding the rated constant power loss corresponding to each switch device as the sum of the fourth rated constant power loss, and determine the result obtained by adding the rated variable power loss corresponding to each switch device as the sum of the fourth rated variable power loss.

[0109] In step f, a target calculation formula is determined based on the first calculation formula, the second calculation formula, the third calculation formula, the fourth calculation formula, and the fifth calculation formula.

[0110] In this implementation, after determining the first calculation formula, the second calculation formula, the third calculation formula, the fourth calculation formula and the fifth calculation formula, the electronic device can determine the target calculation formula based on the first calculation formula, the second calculation formula, the third calculation formula, the fourth calculation formula and the fifth calculation formula.

[0111] Exemplarily, according to the first calculation formula, the second calculation formula, the third calculation formula, the fourth calculation formula and the fifth calculation formula in steps a to e, the target calculation formula determined may be:

[0112]

[0113] Among them, P tot can be the power loss power of the substation, P T It can be the total power loss of each transformer equipment, P BUS It can be the total power loss of each busbar equipment, P SW The total power loss of each switchgear can be expressed as CAP The total power loss of each parallel capacitor device, P IND It can be the total power loss of each shunt reactor device, K SW_c can be the fifth coefficient, K CAP_c can be the first coefficient, K IND_c can be the third coefficient, P Tc It can be the sum of the first rated constant power loss of each transformer device, K BUS_v can be the fourth coefficient, K SW_v can be the sixth coefficient, K CAP_v can be the second coefficient, S can be the actual transmission capacity of the substation, and S n can be the rated transmission capacity of the substation, P Tv It may be the sum of the first rated variable power losses of the various transformer devices.

[0114] In S202, the electric energy loss power of the substation is calculated according to the target calculation formula.

[0115] In this implementation, at any time after the target calculation formula is determined, the electronic device can calculate the electric energy loss power of the substation according to the target calculation formula.

[0116] Taking the target expression in step f as an example, the first coefficient K in the target expression is CAP_c , the second coefficient K CAP_v , the third coefficient K IND_c , the fourth coefficient K BUS_v , the fifth coefficient K SW_c And the sixth coefficient K SW_v It can be considered as a constant. Therefore, after determining the target expression, when the electronic device needs to determine the electric energy loss power of the substation, it only needs to obtain the target expression, the sum of the first rated constant loss power of each transformer equipment, the sum of the first rated variable loss power of each transformer equipment, the actual transmission capacity of the substation and the rated transmission capacity of the substation to determine the electric energy loss power of the substation. It can be seen that this method of first determining the target expression and then determining the electric energy loss power of the substation according to the target expression can further improve the convenience of the method for determining the electric energy loss power of the substation.

[0117] Moreover, after determining the target expression of the substation, the electronic device can also determine the electric energy loss power of other substations with the same design as the substation based on the target expression of the substation, thereby further improving the convenience of the method for determining the electric energy loss power of the substation.
