Problems solved by technology

At the same time, after switching to the cylinder cutting mode, all the exhaust steam from the medium-pressure cylinder of the unit enters the heater at the first station for heating. At this time, the unit can only change the heating power by changing the steam intake of the steam turbine, and the operation is not flexible.

Abstract

The invention discloses a low-pressure cylinder zero-output coupling water heat storage peak regulation heat supply system which comprises a turboset, a heat exchanger, a heat storage water tank, a water supply connector, a water return connector and a switching water path. The turboset is selectively communicated with a first path of the heat exchanger; the heat storage water tank, a second pathof the heat exchanger, the water supply connector and the water return connector are connected through the switching water path so that the heat storage water tank, the second path of the heat exchanger, the water supply connector and the water return connector can be selectively communicated, and the switching water path is provided with a water pump. Excessive heat can be stored in a non-peak-shaving and non-peak-shaving period, and the turboset can be kept in a low-load state by utilizing the stored heat at the peak shaving moment, so that the heat supply requirement can be met, and deep peak shaving can be realized.

Description

technical field [0001] The application belongs to the technical field of electric power peak regulation, in particular, it relates to a low-pressure cylinder zero output coupled water heat storage peak regulation heating system. Background technique [0002] In recent years, my country's wind power, photovoltaic and other renewable energy sources have developed rapidly, and my country's consumption of renewable energy has gradually increased. Now in the heating season in Northeast and Northwest regions, due to the overcapacity of electricity, the problems of renewable energy consumption and power grid peak regulation are very prominent. The reasons for the above problems mainly include: first, the economic growth rate of the northeast and northwest regions is relatively slow, and the growth of electricity consumption is also relatively slow; second, the wind power, photovoltaic and other renewable energy resources are very good in the northeast and northwest regions The cap...
