Study On The Power Quality Management In Power Supply Company And Energy Saving And Loss Reducing Problems

Firstly, this paper commences from the related problems in power quality, which includethe six latest national standards of power quality, and methods for measuring and analyzingeach of them. The power quality on-line monitoring device based on Virtual Instrumenttechnique has been present. Then this paper respectively introduces the mathematic principle,software and hardware of this device. Based on the dates collected from the device which isinstalled on the spot we can find out that region's power quality problems. Secondly, this paper introduces various methods of calculation in wire loss, explains thepresent electric power nets and wire loss condition in Dengkou area, detailed analyzes manyproblems existed in Dengkou countryseat. In this paper many valuable suggestions in bothtechnique and management are put forward to solve above problems. These suggestions willbenefit to reforming, running and managing distribution nets and will also have good valuesto other power supply sections. Finally, contacting power quality , this paper analyzes power loss,which comes from badpower quality, and gives some solutions. In the end we appeal to develop green power supply.
