摘要
针对统一潮流控制器(UPFC)与同步发电机励磁控制系统,结合控制系统控制特性及多指标控制设计理念,选取多个目标状态量线性组合为输出函数,运用多指标非线性控制算法,设计了统一潮流控制器(UPFC)的新控制策略,最后在单机无穷大系统上对其进行暂态仿真。仿真结果表明,所设计的多指标协调控制系统能够很好的解决接入点静态偏移的问题,并有效地控制节点电压和线路的潮流,改善了电力系统的暂态稳定性。
For the unified power flow controller and the excitation control of a synchronous generator, the paper integrates control characteristic of the eontool system and multi-index control design theory to select the linear combinatiors of multiple target conditions as output function;use the multi-index nonlinear control algorithm to design a new countrol strategy of the unified power flow controller. Finally, the transient simulation is carried out to the single unit infinite sys- tem. The simulation result shows that the designed multi-index coordinate control system can solve the problem of insert point static deviation well and can effectively control node voltage and line flow eurrect, inproving the transient stability of the power system.
