Architecture of integrated source and effect measurement system for researching corona phenomena in UHVDC transmission line

For studying the correlation between corona current and corona effect, measuring the source and the effect simultaneously to obtain the complete sets of data could be an ideal way. Integrated source and effect measurement system (ISEMS) is essential for this measurement. After analyzing the implementation and functionalities of ISEMS based on theories regarding to system-of-system and system architecture, a novel architecture of ISEMS is proposed. With this architecture, an ISEMS is developed allowing measurements of corona current, radio interference, audible noise, etc, and it was experimentally tested at UHVDC Test Base of the State Grid Corporation of China. It is proved that the novel ISEMS is capable of measuring corona current and audible noise in more than 20 and 12 different locations respectively, as well as the total electric field at ground level in more than 20 specified positions. The successful measurements indicate that ISEMS with the proposed architecture could be very helpful in researches of corona phenomena and hence contributes to UHV transmission projects.
