Substation Harmonic Analysis Based on Cloud Computing

Abstract

This paper introduces the design and development of a cloud computing system or platform for harmonic monitoring application. In the system, a specially designed interfacing unit at each substation receiving data from measurement units in the substation is responsible for sending data from the substation to the cloud platform through the communication network. Those data may include static, dynamic, transient measurements and states of circuit breakers etc. The cloud platform receives the data from substations, extracts valuable information and allocates them to the specially designed computation algorithms in to perform some advanced applications, one of which the harmonic analysis function is proposed in this paper in order to identify the contents of harmonics and measures to improve power quality.
