Embodiment Construction

[0049] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0050] A control device for heat storage electric boiler equipment in a heat exchange station, installed on the urban heating network, such as figure 2 As shown, it includes a sensor, a signal acquisition module, a measurement module, a calculation module and a controller. The sensor, the signal acquisition module, the measurement module, the calculation module and the controller are connected together in sequence. The sensor collects the grid signal, such as the node voltage, Time-of-use electricity price and distribution period of the power grid; heating network signals, such as heat price, medium flow of primary network and secondary network, supply and return water temperature, and pipeline pressure, etc.; information of electric heating equipment, such as heat storage tank capacity, heat release , heating power, electric heat conversion efficiency, etc....

Abstract

The invention relates to a heat exchange station heat storage type electric boiler equipment control device and method, and the method comprises the steps: considering the constraint conditions of the capacity limitation of a heat storage tank of electric heat compensation equipment, the heat storage and release power, the power grid voltage, the cooperation of a primary heat supply network and a user heat load demand, and comparing a heat critical electricity price with a power grid peak-valley flat electricity price; the electric on-off of the heat storage type electric boiler and the heat on-off of the heat storage tank are controlled by taking economic benefits of heat storage type electric boiler equipment as a target, the operation characteristics of heat storage of the heat storage type electric boiler are brought into full play, the economic operation of the electric heat compensation equipment is improved, meanwhile, the peak, flat and valley electricity price signals of a power grid are responded, the peak and valley difference of the power grid is reduced to a certain extent, and the economic benefit of the power grid is improved. The control method not only meets the actual operation condition, but also meets the heating requirement, and has certain significance in large-scale popularization.

Description

technical field [0001] The invention belongs to the technical field of electric power systems and automation thereof, in particular to a control device and method for heat storage electric boiler equipment of a heat exchange station. Background technique [0002] With the proposal of the "double carbon" goal, clean and efficient energy utilization has become the mainstream of my country's energy development. In the field of heating, municipal central heating is the main body, and the demand is huge. Urban heat exchange stations, as the link of heat exchange between the primary heating network and the secondary heating network, play an important role in improving the quality and efficiency of heating supply. However, at present, the development of municipal heating construction in northern my country lags behind that of urban construction. On the one hand, heat sources have problems of low operating efficiency, high energy consumption and high pollution. On the other hand, du...
