Introduction

As large-capacity UHV DC transmission projects are put into operation one after another, the interconnection between regional power grids is becoming closer, AC and DC, transmission and receiving end, upper and lower power grids The electromagnetic coupling between them has been continuously enhanced, and the characteristics of system integration have become increasingly prominent. When a circuit breaker failure (dead zone) fault occurs in the UHV DC receiving end power grid, If the fault cannot be removed in time, it will cause the UHV DC continuous commutation failure in severe cases, which will bring great impact to the safe and stable operation of the power grid. threaten. The existing circuit breaker failure (dead zone) protection cannot meet the limit cut-off time required for power grid stability. Failure of the station domain specified in this document (Dead zone) protection is an application of the station domain protection system. It adopts a systematic protection concept to collect multi-interval analog and switch signals of the whole station. Information, the use of fiber channel for rapid information exchange between stations to achieve comprehensive discrimination, can isolate the fault in the shortest time under the existing technical Most likely to meet the system stability requirements. This document specifies the functional configuration requirements and technical principles of the station failure (dead zone) protection technology, and proposes the station failure (dead zone) protection. The general structure of protection is helpful to the promotion and application of site failure (dead zone) protection across the country, and has guidance for the development of subsequent site protection. Guide meaning. Technical guidelines for protection of power system station failure (dead zone)

1 Scope

This document stipulates the overall requirements, functions and configuration, technical requirements, auxiliary equipment and two Requirements and tests of the secondary circuit. This document is applicable to the protection of station failure (dead zone) in power plants and substations with dual circuit breaker wiring such as 3/2 circuit breakers. Other types Refer to the use of the protection of the wiring form.
