The optimal configuration of busbar automatic transfer switch (BATS) plays an important role in improving the reliability of power supply in a regional power grid. Taking the outage of Mojiang in Shaoguan power grid as an example, the operating characteristics of the power grid before and after the outage and the cause of the accident are analyzed by using BPA transient stability analysis program. The optimization scheme for improving the reliability of power supply in power grid is analyzed. Action logic and control strategy for BATS of the Mojiang station are designed. The dynamic simulation results show that the proposed scheme is feasible, which can make the power grid recover rapidly under the same fault in different operation modes, and make voltage and frequency recover to the acceptable operating range. The proposed scheme can effectively improve the reliability of power supply.
