针对交流输电潮流控制能力差的问题 ,分析了交流输电中晶闸管控制的可行性 ,建立了交流输电晶闸管串联补偿控制数学模型 ,提出了晶闸管控制交流输电装置的潮流算法 ,即控制变量整定法和控制目标整定法 .控制变量整定法是先给出晶闸管控制交流输电系统 (FATCS)的控制变量值 ,不把FATCS的控制变量作为状态变量 ;控制目标整定法是预先给定FACTS元件的控制目标值 ,把FACTS元件的控制变量作为状态变量 ,从而达到了对电力系统潮流的快速、精确的控制
Aiming at the problem of poor control power flow in AC transmission, the feasibility of thyristor control in AC transmission is analyzed. A mathematic model of AC thyristor series compensation control is established, and the power flow control algorithm of thyristor AC transmission is proposed, that is, control variable tuning and control The target tuning method is as follows: The control variable setting method first gives the control variable value of the thyristor-controlled AC power transmission system (FATCS), and does not regard the control variable of the FATCS as the state variable. The control target tuning method is to predefine the control target value of the FACTS element, Using the control variables of the FACTS components as state variables, a fast and accurate control of the power system flow is achieved
