Problems solved by technology

With the continuous increase of new energy power generation scale and the gradual advancement of the power market, it is difficult to pre-set the adjustment method of generators according to the requirements of dispatching operators. In addition, the change of bus load is also difficult to predict accurately. The difference between different bus loads The proportion of relative change is even more difficult to predict

Abstract

The invention discloses a method for transmission section limit automatic identification and out-of-limit calculation based on xml. The method includes a first step of performing offline transmissionsection limit automatic analysis; a second step of obtaining online data and performing automatic analysis; a third step of performing transmission section limit automatic identification; and a fourthstep of calculating the load rate of each transmission section. The method uses a quantitative evaluation method to map and calculate each section of the transmission sections and the included memberequipment to obtain the operating mode, power limit, and load rate of each section. The method can be used for determining the operating power limit of each transmission section of a power system, and provides a decision-making basis for the safe and stable economic operation of the power grid.

Description

technical field [0001] The invention relates to the technical field of large power grid online simulation and calculation analysis, in particular to an xml-based automatic identification of the limit of a power transmission section and a calculation method for exceeding the limit. Background technique [0002] Transmission section limit is a key indicator for power system dispatchers to monitor the safe operation level of the power grid. Calculation and analysis of power system transient safety and stability section limit power is one of the important contents of power system safe, stable and economical operation and control. Currently, transmission section power limit The calculation method is that the grid dispatching operator first determines the power adjustment mode of the generator and load based on experience, and then through the transient security and stability time domain simulation calculation, finally determines the power limit of the transmission section. In fac...
