Is the substation design good once or twice?

Whether the substation is designed once or twice, it needs strict treatment! Simply put, only one device is a sign of the direction of the circuit. The second time should not only reflect the mutual functional connection, but also realize various functions, such as starting, stopping, current and voltage sampling, locking and interlocking. So we can't simply say good and bad, there is a close relationship between them.

Substation is one of the power supply facilities, where the voltage changes. In order to transmit the electric energy of power plant to a long distance, it is necessary to raise the voltage and turn it into high-voltage electricity to reduce the loss in the transmission process, and then reduce the voltage as needed when it reaches the vicinity of users. The work of raising and lowering the voltage depends on the substation. The main equipment of substation is switch and transformer. According to different scales, small substations are also called substations and distribution rooms. Substation is a transformer, which distributes electricity. Therefore, it is necessary to be as close as possible to the place where there is a lot of electricity, so as to use electricity efficiently, and the voltages will not affect each other.
