Systems and methods for use in identifying and responding to type of grid fault event
First Claim
1. A power module for use in controlling a converter coupled between a power generator and an electric grid, said power module comprising:
- a converter configured to supply an output from a power generator to an electric grid; and
,a controller coupled to said converter and configured to;
disable said converter in response to a grid fault event, such that said converter is gated off;
identify the type of grid fault event after a first predetermined interval from disabling said converter; and
enable said entire converter, when the type of the grid fault event is identified as a low voltage condition.

Abstract
Systems (100), power modules (108), and methods for using in controlling a converter (110) coupled between a power generator (104) and an electric grid (102). A power module (108) includes the converter (110) configured to supply the output from the power generator (104) to the electric grid (102) and a controller (112) coupled to the converter (110) and configured to disable the converter (110) in response to a grid fault event, to identify the type or the grid fault event after a first predetermined interval from disabling the converter (110), and to enable switching of the converter (110), when the type of the grid fault event is identified as a low voltage condition.

9. A power system comprising:
-
a power generator configured to generate a DC voltage; and
,a power module coupled to said power generator and configured to convert the DC output to an AC output and provide the AC output to an electric grid, said power module including a converter, said power module is configured to; detect a grid fault event based on a parameter associated with said converter; disable said converter in response to the detected grid fault event, such that said converter is gated off; identify a type of the grid fault event after a first predetermined interval based on the parameter associated with said converter; when the type of the grid fault event is identified as a phase jump condition, determine if a phase-lock-loop (PLL) module is locked onto the electric grid after a second predetermined interval; and enable said entire converter, after the second predetermined interval, when the type of the grid fault event is identified as a phase jump condition. - View Dependent Claims (10, 11, 12, 13)

14. A method for use by a power module in controlling a converter coupled between a power generator and an electric grid, the power module including a converter and a controller coupled to the converter, said method comprising:
-
detecting a grid fault event as a function of a parameter associated with the electric grid; disabling the converter based on the detected grid fault event, such that the converter is gated off; identifying, at the controller, the type of the grid fault event after waiting a first predetermined interval; and enabling said entire converter, when the type of the grid fault event is identified as a low voltage condition. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)
