发明名称 SYSTEMS AND METHODS FOR SYNCHRONOUS SPEED AVOIDANCE IN DOUBLY-FED INDUCTION GENERATORS
摘要 The disclosure details implementations of apparatuses, methods, and systems for facilitating efficient operational characteristics for wind terminal generators. The system includes features that facilitate protecting the power semiconductors used in the power converters of variable speed power generation systems from excessive junction temperatures. These features may be achieved by implementing a synchronous speed avoidance (SSA) controller implemented to facilitate a determined active control range as an electrical torque/power -generator rotor speed controller. The determined active control range may be centered around a generator synchronous speed. The upper and lower bounds of the active control range are determined based on operational junction temperature characteristics of power semiconductors used within a power converter, reliability characteristics of the power semiconductors and/or current ratings of the power semiconductors.
