| Abstract: |
| In order to monitor the state of UHV Shunt Compensating Capacitor Bank (UHV-SCCB), a newly developed intelligent terminal which can be used for monitoring the current of a single capacitor or a capacitor group unit (under the condition of HV equipotential) is developed. Its specific functions include:fundamental current monitoring, harmonic current content detection, waveform of transient current recording and storage, and wireless communication. The terminal’s technical scheme and working principle are discussed in detail. The terminal’s functional configurations, design procedures and specific circuits are illuminated as well. Furthermore, the relevant key technical difficulties are analyzed deeply. Particularly, management process of power (storage battery included), the special design of specialized measuring CT, criterion of starting recording waveform, and method of implementing waveform recording are focused on. Laboratory experiments and third-party tests are conducted to verify the function realization and the ability of anti-interference. The test result of whole machine shows that the terminal’s functionality and performance can meet the requirements of practical application. This work is supported by Science and Technology Project of State Grid Corporation of China (No. GYW17201600034). |
