Abstract
An inner power plant portion and a heat exchange station portion. The inner power plant portion includes a heat exchanger, a waste heat recovery electric heat pump, an energy-storing electric heat pump, high/low temperature water storing tanks, a heating network heater, a valve and a circulating water pump; the heat exchange station portion includes high/low temperature water storing tanks, an electric heat pump, a heat exchanger, a valve and a circulating water pump; as for the operating method of the device, the device can operate in periods of an electrical load trough, an electrical load flat and an electrical load peak respectively through combination of different valve switches, the high temperature water storing tank is used for balancing the difference between system heat supply amount and heating load, the low temperature water storing tank is used for stabilizing steam exhaust waste heat recovery amount.
