内置Crowbar电路的双馈风电机组短路特性研究
Short circuit characteristics of doubly-fed wind generator with built-in crowbar circuit
摘要
Abstract
As the proportion of wind power installed capacity in the power grid is increasing, the impact of the short-circuit current supplied by the wind power generation system on the relay protection device can not be neglected when there is a problem in the operation of the power grid. When the grid voltage drop greatly,the crowbar protection action to the topological structure of the wind turbine to change this setting of relay protection device of wind power transmission lines of the calculation difficulty. This paper deduces the equivalent circuit of the wind power generator with crowbar protection action, together with the short circuit characteristics and short-circuit current calculation model of doubly fed wind generator. Finally, the validity of the model on line protection device setting calculation is verified in PSCAD simulation platform.关键词
