T/SEPA 001-2020 DC converter station phase selection and commutation device debugging method

Scope

Main technical content: Phase selection closing is achieved by certain means, so that the moving and static contacts of the circuit breaker close at the specified phase angle of the system voltage waveform, effectively reducing overvoltage, reducing arc burning and inrush current, and ensuring that power equipment such as capacitor banks, parallel reactors, and empty-load lines are put into the grid with minimal impact on themselves and the system. In order to standardize the on-site debugging methods of phase selection closing devices for DC converter stations, ensure the quality of debugging, and meet the needs of relay protection personnel, this document is specially formulated. This document stipulates the debugging items and acceptance of phase selection closing devices for DC converter stations, and provides a unified technical specification for the debugging of phase selection closing devices for DC converter stations within the enterprise
