Deep peak shaving system and method for thermal power generating unit utilizing electrode steam boiler system to regulate steam supply

The invention discloses a deep peak shaving system and method for a thermal power generating unit utilizing an electrode steam boiler system to regulate steam supply. A steam exhaust port of a high-pressure cylinder communicates with an industrial steam supply pipeline through a third valve; an outlet of an electric super-heater is divided into two paths, one path communicates with the industrialsteam supply pipeline through a second valve, and the other path communicates with an auxiliary engine steam pipeline through a third valve; a steam extraction port of a middle-pressure cylinder communicates with the auxiliary engine steam pipeline through a fifth valve; a steam outlet of an electrode steam boiler communicates with an inlet of the electric super-heater; a demineralized water pipeline communicates with a water side inlet of the electrode steam boiler through a booster pump; a water tank water outlet in the lower part of the electrode steam boiler communicates with an inner container water inlet in the
