Abstract

The invention discloses a power grid EMS control method and device. The method comprises the steps of: establishing a static CIM model of power grid equipment according to an actual electrical wiring diagram of a power grid; transplanting the static CIM model of the power grid to a controller of a power grid EMS system; acquiring and analyzing measurement data of each switch device in a power grid through an IO channel of a controller so as to determine a connection relationship among devices in a CIM model, and forming an independent topological unit; and collecting and analyzing measurement data of other equipment in the power grid, integrating each topological unit and filtering out the topological unit without a power supply to form an independent topological island. The method and the device can detect the change of a power grid in real time, adapts to the change of the power grid, and guarantees the stability of the power grid.

Description

technical field [0001] The invention relates to the technical field of power grid control, in particular to a power grid EMS control method and device. Background technique [0002] With the continuous expansion of my country's offshore oil industry, the topological structure of offshore oil platform power grids is becoming more and more complex. In order to better improve the power quality and safety and stability of the offshore grid, an EMS control method for the offshore grid is needed. Its functions include monitoring and remote control of key equipment, management and control of generator sets, grid active and reactive power flow and voltage control, grid online Stability control, power grid operation hot standby margin management and comprehensive management and control of key loads, etc., can monitor power grid operation in real time, handle faults in time, avoid power grid decoupling, reduce black start, enhance the shock resistance of the power grid, and improve th...
