Whole network distributed heat storage and supply system and method

Abstract

The invention relates to a whole network distributed heat storage and supply system and method and belongs to the field of heat storage and supply systems. The whole network distributed heat storage and supply system is characterized by comprising a heat supply system, a heat storage system, a control system and a management and control platform, wherein the heat supply system is connected to theheat storage system, and the control system is separately connected to the heat supply system, the heat storage system and the management and control platform; the heat storage system includes a heatstorage tank, an electric shut-off valve, an electric regulating valve and a circulating water pump, wherein a cold water end and hot water end of the heat storage tank are separately connected to theheat supply system through the electric shut-off valve, the electric regulating valve and a circulating water pump. The whole network distributed heat storage and supply system and method have the advantages that novel heating systems of heat storage devices are installed on positions such as users' houses, heat exchange stations, pipe networks, renewable energy source areas, thermal power plantsand regional boiler rooms, and through the mode of combining user sides, pipe network sides and heat source sides for heat storage, not only are the needs of heat sources for peak shaving met, but also the advantages of being narrow in adjustment range, closer to the users, higher in flexibility and the like are achieved.

Description

technical field [0001] The invention belongs to the field of heat storage and heat supply systems, and in particular relates to a whole network distributed heat storage and heat supply system and method. Background technique [0002] At present, the heating industry is generally dominated by planned heating, and under the background of the giant pipe network, there are problems such as oversupply, undersupply, advanced adjustment and lag in heating production, and fine adjustment cannot be realized. In the future, heating production should be developed in the direction of user self-adjustment, that is, timely and appropriate heating should be provided according to the user's heat demand. [0003] There are irregular fluctuations on both the thermal energy supply side and the thermal energy demand side. The load fluctuations on the thermal energy demand side are mainly affected by weather and human behavior factors. The combined heat and power generation on the thermal energy...
