摘　　要：常规相间功率控制器(IPC)是一种静态调节设备,具有鲁棒潮流控制、短路电流限制和两端电压弱影响的良特性,但也存在设备过电压与安装点电压容易越限、各种行性能要求下的控制参数分散性较大、不易实现多种运行能的协调等问题。针对这些问题,该文提出了一种动态可控IPC(DCIPC)的原理结构,使得常规静态IPC 的等效电感、电容和移相环节变成一种连续动态可控的形式,分析了它的4 种控制策略:基于系统全局正常运行信息的性能协调控制策略、基于设备就地局部正常运行信息的性能协调控制策略、基于就地局部事故状态信息的控制策略和设备投入与退出时的控制策略。并在此基础上,分析了各种控制策略对应的参数协调方法以及控制系统的实施方案。数值仿真表明,文中所提策略和方法是可行的,能够动态地协调DCIPC的不同性能。既可指导IPC 的实际运行,提高其运行性能,又可帮助控制人员发现运行中的矛盾,及时提供解决问题的策略和方法。The usual inter-phase power controller (IPC) is a static device, and has the unique properties of robust power flow control, short circuit currents limitation and voltage decoupling. Whereas there are many problems for IPC’s applications, such as over voltage on the components of IPC, overflow of IPC’s terminal voltages, decentralization of control parameters for fulfilling various operation requests, and difficulty in coordinating various operation requests. This paper proposes a principle configuration of IPC with dynamic control properties, the equivalent suscepatances and phase shifting components of which can be changed continuously, termed as Dynamic Controlled Inter-phase Power Controller (DCIPC). Four control strategies of DCIPC are analyzed, which is based on global normal operation information, local normal operation information, local fault information, and for device going into and dropping out, respectively. Parameter- coordinating methods and schemes of control system are also analyzed based on the four control strategies. Case studies on test systems verify the feasibility of strategies and methods. All the work can direct the practical operation of IPC to improve performance and assist the operators to discover the problems in time and provides the appropriate solutions.
