Abstract
A method of reducing cold startup time of a genset which includes an engine and a generator for providing a requested power to a utility grid or load comprises determining if the generator is electrically coupled to a utility grid or load. In response to determining the generator is electrically coupled to the utility grid or load, a speed bias value is controlled in response to the power being produced by the genset. The speed bias signal represents a difference between a target power output and a current power output of the genset. The power of the engine is controlled using the speed bias value.
Claims25
A method of reducing cold startup time of a genset for providing a requested power to a utility grid or load, the genset comprising an engine and a generator, the method comprising:
- determining if the genset is electrically coupled to a utility grid or load;
- in response to determining the genset is electrically coupled to the utility grid or load, controlling a speed bias value based on a difference between a target power output and a current power output of the genset in response to the power being produced by the genset;
- and
- controlling the power of the engine using the speed bias value.
A genset, comprising:
- an engine;
- a generator including a circuit breaker electrically coupleable to a utility grid or load;
- a speed control system;
- and
- a controller configured to:
- determine if the genset is electrically coupled to the utility grid or load;
- and
- in response to determining the genset is electrically coupled to the utility grid or load, generate speed bias data instructing the speed control system to control a speed bias value based on a difference between a target power output and a current power output of the genset in response to the power being produced by the genset;
- and
- control the power of the engine using the speed bias value.
A control device for reducing a cold start time of a genset, the genset comprising an engine, a generator including a circuit breaker electrically coupleable to a utility grid or load and a speed control system, the control device comprising:
- a controller communicatively coupled to each of the generator, the circuit breaker and the speed control system, the controller comprising circuitry configured to:
- determine if the genset is electrically coupled to a utility grid or load;
- and
- in response to determining the genset is electrically coupled to the utility grid or load, generate speed bias data instructing the speed control system to control a speed bias value based on a difference between a target power output and a current power output of the genset in response to the power being produced by the genset;
- and
- control the power of the engine using the speed bias value.
