Abstract
First, the paper analyzes the advantages and disadvantages of all kinds of reactive power compensation technology, and then proposes a principle and integrated control strategy of the composite operation of TSC and SVG, also the paper designs and develops the main controller of Network based composite power quality regulation device, based on RTDS, the real-time digital simulation model of The Device is established, and finally the prototype of the device is developed with the function of filter and split-phase compensation. The main controller determines the cooperative operation of both TSC and SVG, and the switching strategy of TSC. The simulation result in RTDS can verify the precision of the measure system and the validity of the control logic, the prototype has finished the type test according to the national standard.
Highlights
IntroductionWith the rapid development of national economy,the amount and variety of power consumption equipment connected to the distribution network are increasing, which causes the growing decline in the power quality characterized by the large amount of reactive power and serious harmonic pollution, so the effective method in improving power quality is to adopt reactive power compensation technology and harmonic suppression technology [1,2]

Summary
With the rapid development of national economy,the amount and variety of power consumption equipment connected to the distribution network are increasing, which causes the growing decline in the power quality characterized by the large amount of reactive power and serious harmonic pollution, so the effective method in improving power quality is to adopt reactive power compensation technology and harmonic suppression technology [1,2]. The SVG can realize continuous reactive compensation and suppress voltage flicker, but its disadvantages lie in high cost and high-power switch device’s impact on its compensation capacity [3-5]. Xi’an High Voltage Apparatus Research Institute Co. Ltd has developed a novel via compensator——Network based composite power quality regulation device, which consists of several TSC banks and a SVG, by making full use of TSC’s long-term stable reactive power compensation and power harmonic suppression and SVG’s instant fast reactive power compensation, the rapidly continuous large-capacity reactive compensation can be realized, so this device compensates the reactive power and harmonic and has a high performance price ratio compared to counterpart device
