Abstract

The invention discloses a power load unbalance protection method and device for a turboset and electronic equipment. The method comprises the steps that the rotating speed of a steam turbine in the turboset, the prime power of the steam turbine and the output power of a generator in the turboset are obtained; and when the deviation between the prime power of the steam turbine and the output power of the generator exceeds a first threshold value and the rotating speed of the steam turbine exceeds a second threshold value, a high-pressure regulating valve and a medium-pressure regulating valve in the steam turbine set are closed.

Description

technical field [0001] The application belongs to the field of thermal power plants, and in particular relates to a method, device and electronic equipment for protecting unbalanced power and load of a steam turbine unit. Background technique [0002] When the transmission line of the power grid fails, the output power of the generator will suddenly decrease, but the driving power of the steam turbine will basically remain unchanged. The load oscillation of the unit paralleled with the power grid. In order to maintain the stable operation of the power grid, it is necessary to set up the power load unbalance protection of the steam turbine. [0003] In some scenarios, the steam turbine power load unbalance protection is to trigger the steam turbine power load unbalance protection when the deviation between the prime mover power of the steam turbine and the output power of the generator exceeds the set value, and quickly close the high and medium pressure regulating valve of ...
