Abstract:

In order to solve the problems of low efficiency and long time consuming when using BPA electromechanical transient program to simulate large-scale provincial power grid voltage sag, this paper proposes and implements a parallel fast simulation scheme of voltage sag based on multi-core technology. Firstly, analyze the data file of BPA software to obtain the bus and line information of the whole network; secondly, automatically generate a large number of fault information according to the BPA format requirements and write them into the transient stability file one by one; thirdly, call the BPA simulation program in parallel through multi-core technology and store the data of sag results; finally, through the simulation of the whole network line sag of a province, and compare with the current situation The time-consuming comparison of BPA based voltage sag simulation schemes shows that the proposed method can effectively speed up the simulation speed, save time and cost, and provide a large number of reference data for voltage sag research and risk prediction. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
