Ultra High Voltage

A space charge density wireless measurement system based on the idea of distributed measurement is proposed for collecting and monitoring the space charge density in an ultra-high-voltage direct-current (UHVDC) environment. The proposed system architecture is composed of a number of wireless nodes connected with space charge density sensors and a base station. The space charge density sensor based on atmospheric ion counter method is elaborated and developed, and the ARM microprocessor and Zigbee radio frequency module are applied. The wireless network communication quality and the relationship between energy consumption and transmission distance in the complicated electromagnetic environment is tested. Based on the experimental results, the proposed measurement system demonstrates that it can adapt to the complex electromagnetic environment under the UHVDC transmission lines and can accurately measure the space charge density.

Therere two main methods for ultra-long distance transmission: half-wave length alternating current transmission and ultra high voltage direct current transmission. Its described in this paper that the working principle, and operational performance of both technology. In addition a comparison is made in areas of technology and performance including transmission capacity, reactive power compensation, stability and over-voltage. The parameters from the running project and theoretical prediction is used to make an economical comparison among the 1000kV half-wave length alternating current transmission and ±1000kV, ±800kV ultra high voltage direct current transmission.
