【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 of voltage in large smart grid, because the reactive power regulation boundary of voltage is fixed and can not reflect the influence of voltage on reactive power, it is necessary to call on-load voltage tap changer and shunt capacitor bank for voltage regulation many times, and the adjustment accuracy is too low. a fuzzy voltage control algorithm of large smart grid based on TS-PID is proposed, and the mathematical model of voltage of large smart grid is analyzed. The objective function and constraint conditions of voltage quadratic programming in large smart grid are given. The general form of linear PID controller is analyzed, and the open-loop transfer function and closed-loop transfer function of active power channel of large smart grid generator are given. Ts-PID controller combines linear PID control with T 鈮，
