  • Gas turbine overspeed protection method and apparatus, electronic device and storage medium
    Patent number: 12241378
    Abstract: A gas turbine overspeed protection method includes: a power utilization load of a generator is acquired, and a rotating speed value of a gas turbine is acquired; whether the power utilization load suddenly decreases or disappears is judged, and if so, an eddy current retarder is controlled by a controller to simulate the power utilization load to provide a braking torque for the generator; or, whether the rotating speed value exceeds a set speed range is judged, and if so, the gas turbine is controlled by the controller to reduce fuel supply, and a discharge valve of a gas compressor is opened to discharge a high-pressure gas to reduce the power output and the rotating speed of the gas turbine.

  • Main drive control method for glass factories
    Patent number: 10498262
    Abstract: A main drive control method for glass factories, comprising the following steps: (a) providing a first circuit breaker and a second circuit breaker on a power supply loop of an electrical motor, wherein one end thereof is respectively connected to two main drive electrical motors; (b) enabling the first circuit breaker to be connected to a municipal power supply and the second circuit breaker to be connected to a UPS power supply; and (c) enabling the first circuit breaker and the second circuit breaker to be interlocked via a mechanical interlocking mechanism, so that only one of the circuit breakers can be switched on during a normal operation. The main drive control method for glass factories solves the problem that the rotation speed of a main drive electrical motor is incorrect due to the interference on a signal.
