摘要

大规模新能源集中外送系统新能源占比高、耐受直流故障扰动冲击能力低，在源网协调方面存在较为突出的问题。该文分析了我国大规模新能源集中外送系统主要的风险隐患，包括电压波动、频率波动和低频振荡问题。指出大规模新能源集中外送系统源网协调仿真评估的建模重点，包括励磁系统辅助控制环节、发电机涉网保护、含动力系统的发电机调速控制精细化建模等方面。提出了大规模新能源集中外送系统源网协调仿真评估流程及注意事项，可为实际电网源网协调提供参考。

Abstract

Large-scale centralized new energy sending system is a unique form of power grid in China. Due to the high proportion of new energy sources and low tolerance to high-voltage direct current(HVDC) fault disturbance

there are prominent problems in the coordination between source and power network. The major potential risks

such as large voltage fluctuation

large frequency fluctuation and low frequency oscillation were analyzed. It was pointed out that the key problems of modeling include the auxiliary control of excitation system

generator protection concerned with network and generator speed control with dynamic system. The simulation evaluation process and precautions of the source network coordination in large-scale centralized new energy sending system were also proposed

which could be a reference for the actual simulation evaluation operation.
