Whole network distributed heat storage heating 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 heating systems, and in particular relates to a distributed heat storage and heating system and method for the whole network.Background technique[0002]At present, the heating industry generally focuses on planned heating, and under the background of the huge pipe network, heating production has problems such as oversupply, undersupply, adjustment ahead and lagging, and fine adjustment cannot be achieved. In the future, heating production will develop in the direction of users' self-regulation, that is, supply heat in a timely and appropriate amount according to users' heat demand.[0003]Irregular fluctuations exist 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. The cogeneration on the thermal energy supply side is affected by grid dispatching, and industrial waste heat is affe...
