Analysis and application on reactive power compensation online monitoring system of 10 kV power distribution network

Abstract

Data shows that the reactive power compensation devices break down frequently in 10 kV power distribution network. But the failure cannot be discovered in a short time, so lots of manpower and resources are wasted. This paper proposes one method which uses the JST-C20 series Low-voltage Intelligent Capacitors to solve the problem and formulates the reactive power optimization plan for several typical lines based on the reactive power compensation optimization computation. Finally, the article analyzed the validity of this method on voltage quality improvement, energy saving, on-line monitoring and fault diagnosis. © Springer International Publishing Switzerland 2014.
