【Abstract】 As the control object in the substation voltage and reactive control,the OLTC’s adjustment may emerge the voltage instability,even the voltage collapse.In view of the situation, the paper presents the method of using a voltage collapse criterion to warn off the reverse action of OLTC in advance.更多还原
