High voltage shunt capacitor complete set is the mostly used reactive power compensation equipment with higher performance in China

mainly for improving the grid power factor and enhancing supply voltage quality. With the economy development and diversity of power load in China at present and at the background of lots of access of customers from harmonic source

wind power and new energy

the operation reliability of high voltage shunt capacitor is of particularly importance. In this paper

the analysis from such aspects as implementation of the technical guide of the reactive power disposition

construction quality

design specification

influence of grid harmonic contents

fault maintenance

special protection of capacitor

bird and small animal resistance are made

the issue affecting the operation reliability of capacitor is found. For the issues

the improvement measures on the operation and maintenance is proposed and the operation reliability of the equipment is improved.
