摘要
采用多处理器并行技术将复杂的任务分配给不同的处理器 ,通过时间重叠、资源共享等方法快速准确地计算出基于两相系统瞬时实功率和瞬时虚功率的电力系统综合补偿的指令电流。该并行处理系统大大缩短了产生补偿指令的时间 ,并行系统产生补偿指令的时间仅仅是单处理器系统的 1 /2。仿真和实验证明此法可以有效地补偿电路运行中谐波、无功、不对称问题。同时 ,系统具有很好的灵活性 ,当实际情况或对系统的要求变化时 。
In this paper,the parallel technology is applied to power synthetic compensation. By this technology,the com plicated task is divided and assigned to different processing units.With the processing tim es overlapped and the resources shared in the different CPU of the parallel system,the synthetic compensation current instruction based on the instantaneous active power and the instantaneous reactive power can be figured outquickly and exactly.As a result,the processing tim e of the multi- CPU parallel processing system is decreased to only half of that by the single CPU system.Furtherm ore,the simulation and experimental results show that the harmonic,inactive and asymm etry operation in power system can be com pensated effectively.Finally,this system is quite flexible,which can still meet the corresponding requirements when the circumstances or demands are changed.
