南方电网失步解列系统特性RTDS仿真试验研究

对南方电网目前配置的失步解列系统的定值设置及协调配合进行实时仿真研究,建立了南方电网交直流混合实时数字仿真(RTDS)模型,搭建了由RTDS、失步解列系统、功率放大器、直流控制保护装置组成的实时闭环试验系统.试验中模拟了线路故障、直流闭锁及其组合故障,全面测试了严重故障下南方电网失步解列系统动作特性,分析比较了失步解列系统分别在开环控制、闭环控制两种RTDS实时仿真测试模式下的动作规律,并与BPA离线仿真人工判断结果相比较.结果表明针对检验的几种典型严重故障方式,南方电网失步解列系统动作配合正确.试验克服了厂家试验存在的功能单一、离线仿真人工估计等缺陷,是RTDS应用于失步解列系统研究的重大尝试,为进一步将RTDS应用于整个安稳系统实时仿真研究积累了方法经验.

RTDS Simulation Study on the Performance of Out-of-Step Splitting Systems in China Southern Power Grid

The real-time simulation on value setting and coordination of out-of-step splitting systems installed in China Southern Power Grid (CSG) are studied. The closed loop test systems consisting Real-Time Digital Simulator (RTDS), out-of-step splitting systems, power amplifier, real HVDC control and protection equipments are built. Some transmission line faults, HVDC block and their combined faults are simulated and dynamic performances of out-of-step splitting systems in CSG are examined roundly. Operation char...
