Abstract

In view of such issue of compensation strategy of traditional STATCOM in the detection of reactive power current

a kind of new STATCOM reactive power compensation strategy for compensating the front current is proposed. Through the analysis of the STATCOM control method of current

the inner loop control of currentneeds to detect reactive power current for which the process is complicated and multiple modules are used. On this basis

a new STATCOM reactive power compensation strategy based on the front-end current of the compensation point is proposed. The feasibility of this strategy is compared with the traditional reactive power compensation method and such three types of operation modes as fixing reactive power compensation

dynamic switching and load jump which often occur during operation of power system is simulated and analyzed. It is shown by the result that the new type of STACOM reactive power compensation based on the front end current of compensation point reduces the calculation process significantly

improves efficiency

reduces the cost with high dynamic response speed and high accuracy
