Abstract
Voltage support provided by infeed ultra HVDC transmission system is of great significance for reducing the probability of HVDC's blocking or commutation failure and improving operation stability and reliability.This paper demonstrates key technologies and feasibility of pumped storage unit's (PSU's) synchronous condenser operation (SCO) mode.Moreover,a new operation mode which utilizes nearby PSU's SCO to provide voltage support to infeed ultra HVDC transmission system is proposed.The Binjin HVDC in Zhejiang grid and nearby abuilding PSU are considered in simulation analysis,which analyze impact of voltage support provided by PSU in SCO mode on Binjin HVDC system under some typical fault including AC system short circuit.Simulating result verifies that under specific conditions,the PSU's SCO can be utilized to improve HVDC operation reliability,which further improves security and reliability of HVDC multi-infeed Zhejiang power grid.关键词
