Answer / parijaat

power load means the highest power that a plant can use,and
lighting load means the minimum power to maintain emergency
process running in a minimum load.Suppose a steel plant
requires 20 mw power to operate completely,then 17/18 mva
power is its power load,and 2-3mva load to operate emergency
processes in running condition,so it is its lighting load.

Answer / manimaran

The power load is nothing but bulk amount of power(huge
power) using in industry.lighting load means small amount
of power using particularly lighting load only.

When in a large power system if the demand of power is larger than the generated power the frequency of the power system drops.(assume the rated frequency is 50Hz and now it is 49Hz) So does this mean the demand is totally supplied with a lower value of generated power in a lower frequency?
