Optimization Algorithm of Relay Setting Value in Cloud Computing Mode

Due to the continuous expansion of power system network scale,the requirements of relay setting on computer computing and storage capacity are also increasing. For this reason,cloud computing was introduced into the setting calculation of power system relay protection. The application of cloud computing in power system data center was discussed,and the setting calculation platform architecture based on cloud computing was proposed. Then,it studied the optimization method of relay settings in cloud computing mode,established the optimization model of relay settings,and optimized it based on parallel genetic algorithm. Finally,an example was given to demonstrate that the proposed algorithm could effectively meet the sensitivity and selectivity requirements of the protection settings,and fully prove the superiority and rationality of the method.
