摘要
针对现有后备保护方案不能解决潮流转移引起的连锁跳闸问题,提出一种基于广域测量系统(WAMS)的自动切负荷控制策略,使广域后备保护与自动切负荷装置有效结合在一起。通过以4机11节点系统为例进行的潮流转移和减载策略仿真计算,证明此方案具有可行性。
To solve that the existing backup protection can not treat cascading tripping caused by power flow transferring,an automatic load shedding control strategy based on wide area measurement system is proposed,which can associate with existing backup protection and automatic load shedding devices.Taking 4-unit 11-bus system as the case,the power flow transferring and the load shedding are simulated,and simulation results show that the proposed scheme is effective.
