Injection of reactive power into industrial and power systems has been used for many years in order to ; increase power transmission capability of transmission and distribution systems, regulate and stabilize transmission lines, improve power factor as seen from the terminals of the load (generally to unity), avoid undesirable effects of unbalance operation, flicker, voltage sags, etc. In this research project, there are some interesting contributions to this field as follows :(1) Different control system designs are applied for both shunt and series types of VSI based compensators. Two different control systems designed in a-b-c stationary axis frame and d-q synchronously rotating frame were obtained for both of the connection types in this work.(2) It is demonstrated that reference signal tracking control principle has many application areas from reactive power compensators, to UPFC and motor controllers.(3) With the designed controller of the shunt type, the system is effective also on balancing the supply side current. The Series type controller balances well for the unbalanced load voltage.(4) For designing controllers that can handle unbalanced sags or unbalanced loads, it is necessary to decompose the electrical signals to their positive and negative sequences. This method is the decomposition of the signals in α-β frame.(5) NPC inverters are promising for large capacity power converters. This research contributes for improvement of control algorithm for NPC inverters.In the two years' work, the topics have concerned about different types of reactive power compensation systems, and specifically focused on their control principles and operation performances. In the results, compensators are categorized according to their compensation principles of shunt current or series voltage injection. Research results contribute for stabilizing of power supply system and decrease of high harmonics on the system

多年来，向工业和电力系统注入无功功率的目的是：(1)针对并联型和串联型VSI补偿器，采用不同的控制系统设计方案，以增加输配电系统的输电能力，调节和稳定输电线路，提高功率因数(一般为1)，避免不平衡运行、闪变、电压暂降等不良影响。分别在a-b-c定轴坐标系和d-q同步旋转坐标系下设计了两种不同的控制系统。(2)论证了参考信号跟踪控制原理在无功补偿器、UPFC和电机控制器等方面的应用。(3)采用所设计的并联型控制器，该系统也能有效地平衡供给侧电流。串联型控制器能很好地平衡不平衡负载电压。(4)为了设计能够处理不平衡凹陷或不平衡负载的控制器，必须将电信号分解成正序和负序。这种方法是对信号在α-β坐标系中的分解。(5)鼻咽癌逆变器在大容量功率变换中具有广阔的应用前景。在两年的工作中，针对不同类型的无功补偿系统，重点研究了它们的控制原理和运行性能。在结果中，根据补偿原理将补偿器分为并联电流补偿和串联电压注入补偿。研究成果有助于稳定供电系统，减少高次谐波对系统的影响
