Abstract

The invention provides an electrical telemechanical host with a plant-level automatic power generation function. The electrical telemechanical host is connected with a remote signaling module, a remote measuring module, a remote invoking module, a remote control module and an invoking EMS/SCADA main station. The electrical telemechanical host specifically comprises a communication sub-module, a database sub-module, and a full-plant load distribution sub-module, wherein the communication sub-module is used for realizing data communication between the invoking EMS/SCADA main station and the database sub-module and the data communication among the remote signaling module, the remote measuring module, the remote invoking module, the remote control module and the database sub-module; the database sub-model is used for memorizing data required for plant-level AGC (automatic gain control) and carrying out data interaction respectively with the communication sub-module and the full-plant load distribution sub-module; and the full-plant load distribution sub-module generates a control signal of a generator unit active power output based on the data memorized in the database sub-module and sends the control signal to the remote invoking module in sequence through the database sub-module and the communication sub-module. In the electrical telemechanical host, on the basis of sufficiently playing the function of the existing electrical telemechanical host, the quantity of field hardware equipment is reduced, and the operation precision of the data is improved during the unit active adjustment process.

Description

technical field [0001] The present invention relates to the technical field of electrical engineering, in particular, the present invention relates to a power telecontrol host with plant-level automatic power generation control function. Background technique [0002] At present, most of the power grid's scheduling of thermal power plant units adopts the automatic generation control (AGC) direct adjustment method, that is, the load command is sent to each unit, and the load of each unit is directly dispatched. The input of generator set AGC has played a positive and effective role in promoting the safety, stability and economic operation of the power grid. However, the current load dispatching method can no longer adapt to the current low-carbon economy and energy saving and emission reduction because it cannot realize the economical distribution of the load of each unit in the power plant, and at the same time affects the service life and maintenance cost of the generating u...
