UNDER FREQUENCY LOAD SHEDDING IN POWER SYSTEMS (CASE STUDY -- ORISSA SYSTEM)

Abstract

In recent years, due to insufficient generation and increasing deiands in certain power systems in India as well as abroad, the concerned utilities often operate their system at a frequency lower than the rated value of 50 or 60 Hz. Such a recourse to reduction in frequency has been taken in order to decrease the power demands and dnergy consumption of the consumers. The low frequency condition also occurs in a system due to outage of generating units or tie lines. The low frequency operation in power system results in serious damage tothe equipment at the generating stations particularly thermal & nuclear plants, loss of industrial production and_x000D_ damage to consumers' equipments. Further, it causes certain operational problems in interconnected operation of power systems...
