Voltage control method for power transmission and distribution system

摘要

PPROBLEM TO BE SOLVED: To provide a method for controlling the voltage of a power transmission and distribution system which can compensate for a voltage change while an SVR or an OLTC and an existing voltage constant control type SVC are cooperated merely by additionally installing a simple unit at the outside. PSOLUTION: The method for controlling the voltage of the power transmission and distribution system includes a step of compensating the voltage change of the power transmission and distribution system by installing the SVR or the OLTC and a voltage constant control type SVC in the power transmission and distribution system. The method further includes the steps of further installing a voltage signal detection processing unit for detecting and processing the voltage change of the power transmission and distribution system in the power transmission and distribution system, and operating the SVC based on the output signal of this voltage signal detecting and processing unit.
