Thermal protection of electrical generating components under continuous active power generation

摘要

Systems and methods for maintaining the active power production of a fluid turbine and regulating the temperature of an electrical generating component by controlling the reactive power production are disclosed. A thermal parameter of the electrical generating component is monitored. If the electrical generating component exceeds a thermal parameter the reactive power production of the turbine is reduced. A fluid turbine may be de-rated to further reduce an electrical generating component's thermal parameter. A fluid turbine may shut down to further reduce an electrical generating component's thermal parameter. A fluid turbine's power production is re-started when the electrical generating component returns to an acceptable thermal parameter.

1. A method of regulating a temperature of an electrical generating component comprising:
monitoring a thermal parameter of the electrical generating component within a fluid turbine; reducing reactive power production of the fluid turbine if the thermal parameter exceeds a thermal limit; reducing active power production of the fluid turbine if the thermal parameter continues to exceed the thermal limit subsequent to reducing the reactive power production; and shutting down the fluid turbine if the thermal parameter continues to exceed the thermal limit subsequent to reducing the reactive power production and reducing the active power production.
