The Study and Application of High-Voltage Capacitive Equipments On-Line Monitoring System

Abstract:

In recent years, with the development of the smart grid and high-voltage transmission technology, more and more attention has been paid online monitoring of high-voltage capacitive equipment. This paper developed a high-voltage capacitive equipment on-line monitoring system including hardware and software system. Hardware design takes DSP and precision AD as center including signal acquisition and conditioning unit, software part takes modular design including data processing and data query and acquisition control. The system uses zero flux micro-current sensors to collected signals and uses optical fiber to transmission signal, so, the phase measurement error can be control in and signal synchronous transmission can be guarantee. Field application shows that the system data accurate, reliable, stable operation.
