指出了在STATCOM(StaticSynchronousCompensator,静止同步补偿器)控制器设计过程中面临的多控制目标协调问题。除了快速的电压支撑功能以外,STATCOM在电力系统中还应该起到提高暂态稳定极限,阻尼功率振荡等作用。本文从理论分析和数字仿真两方面分析了这些控制目标的矛盾并指出了在各种状态下STATCOM控制器设计的原则,即根据当前时刻系统的状态确定主要的控制目标。在不严重损害其它目标的实现的前提下尽可能提高该控制目标要求的性能。本文根据这些原则设计了STATCOM的协调控制器。数字仿真表明该方法可取得满意的控制效果。

This paper provides an insight into the influences of STATCOM on the stability of power system and presents a rule based controller to enhance the damping of the system as well as maintain the voltage within acceptable limits.The additional damping and synchronizing torque induced on the shaft of generator by STATCOM are calculated in this paper. It is found that the induced damping torque always decreases with the strengthening of voltage control. Moreover, fixed parameter damping controller can be invalid...

This paper provides an insight into the influences of STATCOM on the stability of power system and presents a rule based controller to enhance the damping of the system as well as maintain the voltage within acceptable limits.The additional damping and synchronizing torque induced on the shaft of generator by STATCOM are calculated in this paper. It is found that the induced damping torque always decreases with the strengthening of voltage control. Moreover, fixed parameter damping controller can be invalid or even provide negative damping for certain generator parameters and load conditions. Wherefore, a rule based controller, which employs bang bang, fuzzy logic or fixed parameter PI control strategy according to the operation states of the system, is designed to reconcile the contradiction between voltage and damping control. Digital simulation results show the advantages of the coordinated controller over the conventional fixed parameter PI controller.

研究了STATCOM对发电机同步及阻尼力矩系数的影响,指出并解释了在某些系统参数及运行条件下固定控制参数的STATCOM可能向系统提供零阻尼或负阻尼的现象,分析了STATCOM电压控制与阻尼控制之间的矛盾。在理论分析的基础上,设计了基于规则的协调控制器。数字仿真结果证明该控制方法可在所有的运行条件下有效地提高系统稳定性。这是固定参数控制所无法做到的。

A unified state- space system model is established for a single- m achine infinite- bus power system with STATCOM. Based on the theory and algorithm of inform ation- structure- constrained linear quadratic L Q optim al control,four coordinated control strategies are obtained.They are state- feedback decentralized coordinated control,output- feedback decentralized coordinated control,L Q coordinated control constrained by a given inform ation structure where generator's angular frequency deviation can be used in controlling STATCOM,and a centralized full- scale state- feedback coordinated control. Simulation results show that the four controllers are superior to the separately designed AVR/ PSS excitation controller and PI STATCOM voltage regulator in enhancing system transient and steady- state perform ance. At the same tim e,the decentralized state and output- feedback coordinated control schem es,though inferior to the other two coordinated control schem es,are more applicable because of their low cost and high reliability.

针对单机无穷大系统 ,建立了包含静止同步补偿器 ( STATCOM)的状态空间模型 ,应用给定信息结构约束下的最优控制理论和算法 ,设计了 4组 STATCOM与发电机励磁的协调控制器。它们的控制规律分别是 :状态反馈的完全分散协调控制、输出状态反馈的完全分散协调控制、STATCOM处可以反馈机组角频率偏差的特定信息结构下的 LQ协调控制、全状态反馈的集中型最优控制。仿真结果表明 ,与独立设计的 AVR/PSS励磁控制器和电压偏差 PI调节型 STATCOM控制器相比 ,上述 4组协调控制器能更加有效地提高系统暂态稳定性能。同时 ,完全分散信息结构的状态和输出反馈控制的控制性能稍次于其他两种协调控制规律 ,但由于它们实现代价低、可靠性高 ,更易于实际应用
