Frequency Control in Interconnected A.C. Systems through HVDC Link Using Artificial Intelligence
Journal Title: International Journal of Engineering, Science and Mathematics - Year 2011, Vol 1, Issue 4
Abstract
The Load frequency control in HVDC system has gained importance with the growth of interconnected systems. Hence greater reliance is being placed on the use of special control aids to enhance system security, facilities and economical design, and to provide greater flexibility of the system operation. Hence the need for bulk power transmission has shifted the interest to the HVDC transmission system viz-a-viz the EHV-AC system. Further it possesses the art of smart and useful application of controlled rectifiers and inverters. The controlled inverter operation can successfully modulate the power flow in HVDC link, leading to fulfillment of power demand in A.C. network, caused by sudden rise in loads. This in turn enables the restoration of power frequency in A.C. network. Due to frequent sudden loading and unloading of A.C. networks the frequency in the network continues to be always away from standard power frequency value. In this paper we have developed a controller which maintains the power frequency in A.C. network. Further there is a rich scope of saving of energy and yet maintaining the power frequency in A.C. networks by way of electronic switching of thyristors.
