摘要:
Disclosed herein are systems and methods for rotor angle measurement in an electrical generator. According to one embodiment, an intelligent electronic device may comprise control logic configured to generate a reference signal and to generate a rotational position signal based upon an indicator of a rotational position of a rotor in an electrical generator. The control logic may further be configured to detect a relative shift between the reference signal and the rotational position signal and to determine the rotational position of the rotor based upon the relative shift. A power angle of the electrical generator may be calculated based upon the rotational position of the rotor. According to certain embodiments, the control logic may further be configured to generate a control instruction to reduce the power angle in response to determining that the power angle exceeds a threshold.
