4 General requirements
4.1 In addition to the implementation of GB 26860, the on-site work of smart substations should also comply with the provisions of this standard on secondary safety measures.
4.2 On-site operators should understand the working location, scope of work, electrical main wiring, related primary equipment and secondary equipment operation, and be familiar with
Relay protection, power grid security automatic devices and related secondary circuits, fully assess the impact of field operations on related secondary equipment or circuits.
4.3 The on-site work should comply with relevant regulations or rules such as work tickets, operation tickets, secondary work safety measures (tickets), standardized operations, and risk identification.
system.
4.4 The management and control of smart substation configuration files should be done well.
4.5 On-site work should comply with relevant regulations and systems for information security, and dedicated computers should be used for information operations such as online and file copying.
And secure storage media.
4.6 In the process of on-site work, in the event of an abnormal situation or a circuit breaker tripping, the work should be stopped immediately, and the status quo should be maintained, pending investigation of the cause. determine
It has nothing to do with this job and can only continue to work after getting permission. If the abnormal situation or the tripping of the circuit breaker is caused by its own work, the site should be kept
And immediately notify the operation and maintenance personnel for timely processing.
