摘要：Many different power frequencies were used in the 19th century. Very early isolated AC generating schemesused arbitrary frequencies based on convenience for steam engine, water turbine and electrical generator design.Frequencies between 16⅔ Hz and 133⅓ Hz were used on different systems. In this paper frequency deviation problemassociated with load frequency control is evaluated. It is seen that Integral Controller is required to stable the frequencyby properly selecting control parameters of the dual mode controller. The primary reason for accurate frequency controlis to allow the flow of alternating current power from multiple generators through the network to be controlled. Thetrend in system frequency is a measure of mismatch between demand and generation, and so is a necessary parameterfor load control in interconnected systems.
