Study on The Operation Scheme of One Key Sequential Control in Double Bus Line

In this paper, the traditional substation main wiring form for double bus re-verse bus sequence analysis, first analyzed the advantages and disadvantages of the two typical reverse bus sequence, and pointed out which traditional substation according to the actual site is more suitable for the bus reverse op-eration. Since the one-button sequential control application of smart substa-tion is carried out in accordance with the preset program and gradually, the operation efficiency of bus reversal is no longer limited by factors such as artificial and terrain in traditional bus reversal. On this basis, ETAP software is used to simulate the power flow distribution of two typical traditional bus reversal operations under different parameters. According to the comparison of the change of line current value in the process of bus reversing, the two typical bus reversing sequences are judged to be the most suitable for the one-key down-control bus reversing operation.
