Study of transient voltage stability for distributed photovoltaic power plant integration into low voltage distribution network
摘要
Abstract
A typical system simulation model of distributed photovoltaic power station is established by using MATLAB SPS, which is connected to 0.4 kV low voltage distribution network. The effects on PV power station exit bus transient voltage stability when short circuit, flashover and disconnection faults occur in cable lines, after PV has connected into the distribution network, are investigated by using time domain simulation method. When short-circuit and disconnection fault of cable line occurred, the PV power station exit bus voltage amplitude will increase continuously and lost stability. However, when flashover fault has occurred, inputting reclosure can make the PV power station exit bus voltage recover quickly. When light intensity has greatly dropped, PV power station exit bus voltage amplitude will drop, whose degree is mainly determined by the magnitude of active power output in normal operation. Generally, when PV output has tens of kilowatts and below, light dump won't lead to PV power station exit bus voltage unstable or collapse.关键词
