Calculation Model for Short-circuit Current of Wind Power Field for Power Grid Planning
摘要
Abstract
On the basis of analyzing short-circuit current characteristic of the wind power field and control principles for wind power generators, this paper discusses a kind of calculation model for short-circuit current of the wind power field.It firstly analyzes the calculation model short-circuit current of different typed single wind power generator and provides computation method for equivalent reactance aiming at the situation of different types of wind power generators.Then in allusion to influence of the collector system, it deduces calculating method for equivalent reactance of integrated circuit.Finally, it comprehensively considers factors of different types of generators in the field and influence of the collector system and establishes the calculation method for short-circuit current of the whole wind power field.Simulation results indicate that compared with the detailed model, value of short-circuit current worked out by using this model is larger, which means more favorable in ensuring safe and stable operation of the system when selecting electrical equipment and conductors.Meanwhile, error of this model can meet precision requirement for engineering application of calculation on short-circuit current of the wind power field.关键词
