Summary: | The invention discloses a heat supply unit heating steam extraction system coupled with a low-pressure bypass and an operation method. The heat supply unit heating steam extraction system includes a heating steam extraction mother pipe, a heating steam extraction branch pipe, a reheat steam input pipe, a steam recovery pipe, a three-stage temperature-decreased pressure reducer, a steam condenser,a manual isolation valve, a first electric isolation valve, an electric pressure regulating valve, a second electric isolation valve, a third electric isolation valve, a desuperheater, a desuperheating water input pipe, an electric desuperheating water isolation valve and an electric desuperheating water flow regulating valve. The operation method comprises the steps that during the deep peak regulation, the third electric isolation valve is closed, the manual isolation valve, the first electric isolation valve, the second electric isolation valve and the electric pressure regulating valve areopened, and the desuperhe |
