Survey and development on fault diagnosis in power systems
In this paper,based on the deeply analysis of diagnosis information structure in power systems,study fruits within the domain at home and abroad are surveyed.And using a simple diagnosis example,the ideas and characteristics of several primary models for fault diagnosis are described and analyzed in detail.Based on the existing studying productions and combined with the developing actuality of many aspects power system and information technology,the existing study limitations are presented and the developing direction of fault diagnosis in power systems is analyzed.
Air conditioning power load is one of major factors having led to nationwide power supply shortage in recent years.District cooling can reduce the air conditioning power load.It is a method to overcome the shortage of power.Goverments should make efforts to generalize the district cooling to save energy.
