Description

Technical field [0001] The invention relates to the field of electrical automation in a power system, in particular to a layered electrical monitoring system in a power plant. Background technique [0002] With the technological advancement of the power industry, the automation level of power plant operation is increasing day by day, requiring power plant boilers, steam turbines and electrical to achieve integrated operation, which includes not only boiler, steam turbine automation but also electrical automation. The electrical part of the power plant is divided into the plant power part, the network control part and the generator and transformation unit part. Among them, the auxiliary power and the generator-transformer group are directly related to the production and operation of the power plant: the network control part is an important part of the connection between the power plant and the transmission grid. [0003] At present, most power plants have DCS systems that focus on...
