摘要
针对在对大型智能电网电压进行模糊控制的过程中,由于电压的无功调节边界是固定的,无法反映电压对无功的影响,导致需要多次调用有载调压分接头和并联电容器组进行电压调节,调节精度过低,提出了一种基于TS-PID的大型智能电网电压模糊控制算法,分析了大型智能电网电压的数学模型,给出了大型智能电网电压二次规划形式的目标函数以及约束条件.分析了线性PID控制器的一般形式,给出大型智能电网发电机有功功率通道的开环传递函数以及闭环传递函数.TS-PID控制器将线性PID控制与T-S模型结合起来,通过局部完成全局的非线性控制,降低了电压调节次数.介绍了仿真实验结果.
Abstract
In the process of fuzzy control for large-scale smart grid voltage,the fixed reactive voltage regulating boundary makes it impossible to reflect the influence of voltage on reactive power; consequently,on-load voltage regulating taps and parallel capacitor groups are frequently demanded for voltage regulation,leading to low regulation accuracy.Therefore,this paper puts forward a voltage fuzzy control algorithm for large smart grid based on TS-PID.The mathematical model for large smart grid voltage is analyzed; the objective function and constraint conditions in quadratic programming form for large smart grid voltage are defined ; the general form of the linear PID controller is analyzed;the open-loop transfer function and the closed-loop transfer function are defined for large smart grid generator active power channel.TS-PID controller combines the linear PID control with T-S model,and reduces the frequency of voltage regulation through local nonlinear control.The simulation results show that the proposed algorithm has high precision and effectiveness.
