Abstract

The control and protection system of converter valve is the core equipment of HVDC control and protection system, which is located in the lowest layer of layer distribution control and protection system. The working principle, on site test and operation condition of control and protection system for converter valve at Yulong Station pole Ⅱ low end in Jingping-Sunan ±800 kV UHV DC are presented. The equipment was put into operation for the first time with independent intellectual property.

Key words

converter valve / control and protection system / valve base electronics (VBE) / thyristor trigger and monitor unit (TTM) / project commissioning
