Load-frequency control system

摘要

This invention provides for regulating the generation of a generator at a local power station whose governor receives control signals from a central load dispatcher effective to change the generation so long as there is a change in generation required to meet desired system conditions and wherein a signal representative of actual generation of the generator is fed back to the load dispatchers office. The improvement provides means for producing a signal representative of the ratio of the throttle pressure set point to the actual throttle pressure as well as means for multiplying the signal representative of actual generation by that ratio and supplying the product as the sole feedback to the load dispatcher for determining the control signals to the governor.
