摘要
针对高速铁路功率调节器(RPC)运行中存在的瞬时欠功率问题,提出一种超负荷下的补偿策略来实现RPC的不完全补偿。首先分析不完全补偿原理,构建约束条件最大补偿电流,引入有功补偿系数和无功补偿角度,重点分析RPC最高补偿电流下的补偿策略,为RPC在超负荷下的补偿提供思路。最后,Matlab仿真和小功率平台验证了算法的有效性和合理性。
In order to solve the problem of instantaneous under power due to the operation of high-speed railway static power conditioner（RPC）, a compensation strategy under overload is proposed to realize incomplete compensation of RPC.Incomplete compensation principle is analyzed,the constraints of maximum compensation current is constructed,the introduction of active compensation coefficient and reactive power compensation angle are proposed.Compensation strategy of RPC under the highest compensation current is analyzed to provide ideas for compensation under the overload of RPC.Finally,Matlab simulation and small power platform verify the effectiveness and rationality of the algorithm.
