Based on the "physical distribution and logical integration" architecture of new generation power grid dispatching and control system, the global analysis and decision-making services are deployed in multiple analysis and decision-making centers of different locations. Multi-active technology is introduced to ensure the stable and reliable operation of the system and achieve multi-center load balancing. The implementation of global load diversion mechanism based on scenario and service state in the multi service environment is introduced, which can complete the service access diversion and quickly detect the center failure and complete the service access center switching according to the characteristics of the new generation power grid dispatching control system. The problem is solved that the traditional multi center load diversion mechanism under the C/S architecture of the control system can not be applied to the new generation of power grid dispatching control system, and the switch is slow when the center fails. It realizes that the client access can be divided according to the application service distribution. Fast switch is applicable to the application that all centers provide peer-to-peer services, and also supports the application that provides master/slave services.
