摘要:  随着特高压直流(ultra high voltage direct current, UHVDC)输电的快速发展,当前我国逐步形成了强直弱交的混联电网,直流系统闭锁故障给交流系统的安全稳定运行带来了巨大挑战。混联电网故障后的紧急控制严重依赖于电网仿真结果的准确性。因此,准确的直流故障模型和仿真分析方法至关重要。在已有直流故障功率模型的基础上,研究了特高压直流闭锁在电力系统分析综合程序(PSASP)中的交互仿真实现方法。首先介绍了PSASP现有自带模型存在的不足,然后基于直流故障功率模型给出了直流故障交互仿真方法的步骤及原理,通过MATLAB及VB编程将直流故障功率模型注入PSASP中,并不断调用PSASP的暂态稳定程序,实现与PSASP的交互仿真计算。最后,通过对实际电网直流闭锁故障进行仿真复现,验证了该交互仿真方法的有效性及准确性。

Abstract: With the rapid development of UHVDC, the hybrid grid with strong DC and weak AC system is gradually forming in China. The DC system blocking fault brings great challenges to the safe and stable operation of the AC system. The emergency control after failure in a hybrid grid is heavily dependent on the accuracy of the grid simulation results. Therefore, the accurate DC fault models and simulation analysis methods are essential. On the basis of the existing DC fault power model, the interactive simulation method of UHV DC blocking in Power System Analysis Integrated Program (PSASP) is studied in this paper. Firstly, shortcomings of the existing self-contained DC model in PSASP are analyzed. Then the steps and principles of DC fault interactive simulation method are given on the basis of DC fault power model. The DC fault power model is introduced into PSASP through MATLAB and VB programming. Transient stability program of PSASP is called continuously to realize interactive simulation calculation. Finally, the effectiveness and accuracy of the simulation method are verified by the simulation of DC blocking fault in an actual power grid.
