Study on Low Power Consumption of Space Charge Density Measurement System under HVDC Transmission Lines

Abstract

Zigbee-based space charge density measurement system is widely used in space charge density measurements of high voltage direct current (HVDC) transmission project. In practice, the power consumption of the space charge density measurement system is a key constraint of the device performance. According to the distribution characteristics of wireless communication unit of space charge density measurement system, the low-power operation status transition mechanism and the influence of communication distance and working environment on power consumption are analyzed. At the end, the low-power energy management strategy is developed. The proposed strategy effectively improves the performance of space charge density measurement system.
