摘要： A load protection system for a turbine is provided. The turbine has a load floor representing a lowest allowable load the turbine generally operates above. The turbine supplies power to an electrical grid. The grid has a grid frequency where as the grid frequency increases the turbine sheds load. The load protection system includes a controller in communication with the turbine and the electrical grid. The controller has a memory for storing a commanded target turbine load. The commanded target turbine load is the load the turbine operates at the load floor. The controller includes control logic for sending a flag to a variable rate limiter and a commanded load control block. The variable rate limiter and the commanded load control block generally prevent the turbine from shedding load and operating below the load floor once the flag is received.
