英文摘要:

      Because of a lot of feeding of distributed new energy and the improvement of the quality of the users power supply,intelligent power distribution substations are required to provide more flexible，fast and reliable protection and control functions.Summarized the deficiencies of the existing substation microcomputer comprehensive security system,and for the protection and control requirements of the domain of intelligent power distribution substation，the new CAN communication protocol is designed and implemented.For frequency measurement problems,by hardware circuit sine wave converter to achieve accurate measurements，and ultimately monitoring center can quickly and accurately collect and analyze real-time status information in runtime，and can set the setting value parameters，quickly rule grid failures or problems.In the actual operation detection,the performance of this system is stable and reliable.
