随着新能源的大规模并网,运行方式的时变特性增强,对在线紧急控制策略提出了新的要求。首先,基于扩展等面积准则,分析了惯量比、新能源故障穿越特性对新能源短时波动后等值发电机轨迹的影响,给出了新能源短时波动对控制影响的最恶劣场景。然后,推导了最恶劣场景下紧急控制时刻等值发电机电磁功率突变量计算公式,进而快速得到紧急控制临界量。最后,制定了故障发生后根据实际运行方式字匹配相应控制策略的方法。仿真结果验证了所提方法的准确性和有效性,减少了在线紧急控制在新能源短时波动场景下的欠控风险。
With the large-scale grid connection of renewable energy
the time-varying characteristics of operation modes are enhanced
which puts forward new requirements for online emergency control strategy. First
based on the extended equal area criterion
the influence of inertia ratio and fault crossing characteristics of renewable energy on equivalent generator trajectory after short-term fluctuation of renewable energy is analyzed
and the worst scenario of the influence of short-term fluctuation of renewable energy on control is given. Then
the formula for calculating the sudden change of electromagnetic power of equivalent generator at the emergency control time in the worst scenario is derived
and the emergency control critical quantity is quickly obtained. Finally
the method of matching the corresponding control strategy according to the actual operation mode word after the fault occurence is developed. The simulation results verify the accuracy and effectiveness of the proposed method and it can reduce the under-control risk of online emergency control in the short-term fluctuation scenario of renewable energy.
