Embodiment Construction
[0031] See figure 1 Now, the method of the present invention is described in detail by taking the power supply area of a 220 kV substation as an example.
[0032] The online real-time statistical method for the proportion of the electricity industry in the 220 kV substation is carried out according to the following steps:
[0033] Step 1. Statistical information about the 10 kV lines in the power supply area of the 220 kV substation:
[0034] (1) List the 10 kV lines in the power supply area of the 220 kV substation one by one. The 10 kV lines in the power supply area of the 220 kV Jiawan Xiao substation include: Shanqiao Line 322, Shanjiang Line 412, Shanjiang II Line 326 , Shanzhen Line 324, Shan Nitrogen Line 408 and Line 1, the names of the above lines are shown in the first column in Table 1;
[0035] (2) Online statistics on the real-time active load of the 10 kV line outlet switches, use the energy management system of the regional electric power bureau to onl...

The invention discloses a 220KV transformer substation electricity-using industry composition proportion online real-time counting method. The method includes: step 1, counting related information of 10KV lines belonging in a power supply area of a 220KV transformer substation; step 2, calculating an electricity-using industry proportion of the 10KV lines; step 3, calculating real-time total electrical load in an online manner; and step 4, calculating an electricity-using industry composition proportion of the 220KV transformer substation in an online and real-time manner. By the method, the electricity-using industry composition proportion of the 220KV transformer substation can be counted in an online and real-time manner, so that problems of large denaturation and randomness and difficulty in knowing the electricity-using industry composition proportion when the 200KV transformer substation is loaded are solved, labor intensity is greatly reduced for personnel to manually count the transformer substation electricity-using industry composition proportion, cost is saved, counting errors caused by personal errors are reduced, and counting accuracy of the electricity-using industry composition proportion is greatly improved.
Description
technical field [0001] The invention belongs to a statistical method of a power system, in particular to an online real-time statistical method for the proportion of electricity consumption in a 220kV substation. Background technique [0002] Power system simulation calculation is an important work in dispatching operation, and it is the main basis for formulating the operation mode and safe operation of power grid. Therefore, reliable and accurate simulation calculation results are the basic premise of dispatching operation decision-making. As one of the important components of the power system, the accuracy of its model parameters directly affects the simulation results of the power grid. How to accurately grasp the power system load model is particularly important. The statistics of load characteristics of substations is an important basic work in the load modeling of the statistical comprehensive method. Whether the information needed to truly reflect the proportion of ...
