PLANNING OF PEAKING HYDRO POWER IN A MIXED POWER SYSTEM

Abstract

The main reasons for considering the advisability of installing peak generating units are that a significant part of installed capacity has a reserve function only and has got reduced utilisation. Reduced efficiency at part load arks slow response t,. load variations makes thermal units unattractive for peaking operation. Hydro-electric units are best suited for peaking because of its quick starting and, fast loading characteristics. It can be conventional development if suitable sites available, otherwise we can go for pumped storage. Pumped storage requires only make up water for evaporation losses as the same water is circulated between upper and lower reservoirs. Old convent-ional stations can be redeveloped as peaking station or can be converted to pumped storage station at comparatively shorter time and cost...
