摘要
针对直流输电系统拓扑结构变化频繁的特点,提出一种交直流分割并行的电磁暂态数字仿真方法,避免了直流输电系统拓扑结构变化对电力系统其他部分的影响。在CIGRE标准算例上所做的测试表明,该方法计算结果正确,计算速度快。该方法具有计算效率高、网络分割灵活等特点。该方法的提出和实现,为进一步解决直流输电系统的电磁暂态仿真的实时性及采用数字仿真系统进行直流输电控制保护装置的闭环仿真试验奠定了基础。
Aiming at frequent change of topology of HVDC system, a partition and parallel method for digital electromagnetic transient simulation was presented in the paper, which avoided the influence of topology change of HVDC system on the other parts of the power system. Testing results on CIGRE first benchmark model for HVDC system show that with this method correct results and fast computation speed are obtained. The method has the advantages of high efficiency and flexible network partition. The presentation and realization of the method lays the foundation of further research on solving real-time performance of elctromagnectic transient simulation of HVDC system and carrying out closed-loop simulation test of HVDC control and protection devices based on digital simulation system.
