Analysis on influence of Qinghai Henan DC operation on line loss of Qinghai main network

摘要

In order to accurately calculate the main network line loss of power system, this paper designs a main network line loss calculation method based on power flow algorithm. Taking Qinghai main network as an example, this paper calculates and analyzes the influence of different power output of Qingyu DC near area on the line loss of Qinghai main network. The research results show that this method can realize the accurate calculation of the main network line loss of power system, and the line loss rate of Qinghai main network increases with the operation of Qingyu DC. This method provides a basis for efficient analysis of the main network line loss.
