Study On On-Line Insulation Monitoring System Of High-Voltage Capactive Equipment In Substation

In this paper, further researches on on-line monitoring technique and system are given. Frame of an advanced on-line insulation monitoring system is designed. Problems of traditional measuring methods are analyzed and a new method based on the theory of voltage-dividing capacitor is brought forward. To extract fundamental wave in signals efficiently, a new calculation method of dielectric loss based on ANN is introduced in detail. B/S mode is applied to realize insulation information inquiry system in WEB style. An integrated on-line insulation monitoring system of high-voltage capacitive equipment is designed and developed, and has been debugged in laboratory. The impact of operation is all right.
