Controller Parameters Calculating Method of DC Voltage Loop for DC Grid
摘要
Abstract
The reasonable parameters in constant DC voltage controller are the prerequisite of DC grid for effectiveness operation. Combined the network equation of DC grid with the small signals mathematical model of single converter’s DC output voltage based on Thevenin equivalent model, the generic small signals mathematical model of DC grid was established. In order to achieve the quantitative calculation of controller parameters in the outer loop of constant DC voltage control station, an equivalent method was proposed in this paper. This method, which gives convenience to realize the parameters quantitative calculation of dc voltage controller, can reduce the order of original DC grid mathematical model greatly with scarcely influence on the operational performance of DC grid. Based on a five-terminals dc grid, an electromagnetic transient simulation model and small signals mathematical model calculating program for DC grid were established, the simulation results of which verify the correctness of the small disturbance model and the parameters quantitative calculating method.关键词
