Abstract
A power limiter system is described. The power limiter system is configured to receive a phase locked loop (PLL) error signal; analyze the PLL error signal to identify an occurrence of a grid contingency event; generate a first power command signal corresponding to an occurrence of the grid contingency event; and, transmit the first command signal to a converter interface controller. The system further includes a memory configured to store at least one variable that corresponds to the PLL error signal upon identification of an occurrence of the grid contingency event.
Claims19
A grid-dependent power limiter system comprising:
- a power limiter configured to:
- receive a phase locked loop (PLL) error signal;
- analyze the PLL error signal to identify an occurrence of a grid contingency event;
- generate a first power command signal corresponding to an occurrence of the grid contingency event;
- and,
- transmit the first command signal to a converter interface controller;
- a voltage regulator configured to:
- receive a terminal grid voltage feedback signal;
- generate a second power command signal based at least partially on the terminal grid voltage feedback signal;
- and,
- transmit the second power command signal to the converter interface controller;
- and,
- a memory configured to store at least one variable that corresponds to the PLL error signal upon identification of an occurrence of the grid contingency event.
A power limiter system for reducing pole-slipping within an electric generator coupled to a power grid, said system comprising:
- a power limiter configured to:
- receive a phase locked loop (PLL) error signal;
- analyze the PLL error signal to identify an occurrence of a grid contingency event;
- and,
- generate a first power command signal corresponding to the occurrence of the grid contingency event;
- a power regulator coupled to said power limiter, said power regulator configured to:
- receive the first power command signal;
- generate a second power command signal based at least partially on the first power command signal;
- and,
- transmit the second power command signal to a converter interface controller;
- and,
- a memory configured to store at least one variable that corresponds to identification of the occurrence of the grid contingency event.
