Under the new operation management mode of the large power grid, in order to meet the requirements of the centralized monitoring of emergency control device for provincial and district level dispatching agencies, this paper fully draws lessons from the achievements of the construction of the integrated system of regulation and control, puts forward the construction of provincial level power grid emergency control equipment monitoring system of the overall train of thought and basic framework of collaborative according to the dispatching management scope of device layered access principle. Then the application function module and implementation scheme are elaborated such as data acquisition, device data and status monitoring, real-time alarm, operation management, remote operation, data longitudinal interaction combining the characteristics of emergency control equipment and professional requirements. Lastly, the application of this system in Heilongjiang-daqing two-level power grid is introduced.
