Study on influence of HVDC commutation failure on AC line protection Part one: modeling and simulation of Shandong Grid with DC feed-in system based on EMTDC
摘要
Abstract
Ningdong-Shandong HVDC project will be put into operation, which is a challenge to the security and stability of Shandong power grid, so it becomes more important to research AC-DC system interaction. In PSCAD environment, the electromagnetic transient simulation model of Shandong power grid is established, including the simplified modeling of Shandong AC system and the detail modeling of Ningdong HVDC system. Based on the DC model, the static responses characteristics and transient response characteristics under common faults of DC transmission system are simulated and analyzed. The simulation results show that control system of HVDC transmission system has steady and fast response characteristics and also verify the correctness and validity of the established model. The power flow distribution in Shandong power grid and three phase short circuit currents of the bus in main stations are adjusted and checked to ensure that the data generally agree with the corresponding data in PSASP environment and the steady-state and dynamic characteristics of the established model are nearly the same as those in actual network.关键词
