摘要

风电进入低电压穿越状态后会造成有功扰动，目前运行的风电机组具有良好的低电压穿越能力，能够在故障后不脱网运行，因此有功扰动形式不再完全等效为阶跃，而是在阶跃后存在斜坡恢复。目前，针对有功斜坡恢复情况下的系统频率量化特性研究较少。为此，在电力系统简化频率闭环模型的基础上，引入参数风电占比，再将闭环频率模型进行开环简化，进而通过开环模型推导出频率的解析表达式，并在表达式的基础上计算得到系统的最大风电占比。最后，在Matlab/Simulink和PSCAD/EMTDC电磁暂态仿真软件环境下分别验证开环方法和所推表达式在含风电电力系统低电压穿越下的有效性。

Abstract

When the wind power enters the low voltage ride through state

it will cause active power disturbance. Nowadays

wind turbines possess excellent low voltage ride through ability and can run without off-grid operation after a fault occurs. The active power disturbance form is no longer strictly equivalent to a step; instead

it exhibits a slope recovery after the step. The current research on the system frequency quantization characteristics in the case of active slope recovery is limited. Therefore

the introduction of wind power into the closed-loop frequency model is performed on the basis of simplifying the frequency closed-loop model of the power system

and the model is simplified to an open-loop one by fitting function method. The analytical expression of the maximum frequency variation is then derived through the open-loop model

and the maximum wind power ratio of the system and the minimum droop coefficient of wind power participating in frequency regulation are calculated based on this expression. Finally

the effectiveness of the open-loop method and the proposed formula under the low voltage ride through of the power system with wind power is verified through simulations using Matlab/Simulink and PSCAD/EMTDC electromagnetic transient simulation software.
