Research and Design of the Remote Monitoring System for Power Quality in Wind Farms

Abstract

Rapid development of wind power generation and increasing growth of installed capacity of wind turbines make it necessary to study the power quality in wind farms. To monitoring the power quality in wind farms automatically and in real time, this paper presents a remote monitoring system for power quality based on LabVIEW software and Internet technology. The remote panel technology in LabVIEW and the Browser/Client (B/S) mode are adopted. This system mainly consists of monitoring hardware devices, the server, LabVIEW application software and remote clients. In the system, the remote clients in monitoring center workstations can monitor in real time power quality parameters of each wind turbine in wind farms through the VI control panel in the Internet browser. Thus it enables to improve automation level of wind farms and reduce operation and maintenance cost. The feasibility and coordination of the developed system are validated by experimental simulating results in the laboratory environment.
