Energy Calculations of Large Buildings
www.me.ua.eduThe "kW" column is the electric power demand of the heat pump at a given condition, obtained from: kW = q (Btu/hr)/(COP * 3412 Btu/kWh) where q is the building load for conditions where PLF < 1 and q is the heat pump capacity for conditions where the heat pump is operating continuously. The “kWh” column is the product of kW and the

Power System Analysis
research.iaun.ac.irPOWER SYSTEM is predominantly in steady state operation or in a state that could with sufficient accuracy be regarded as steady state. In a power system there are always small load changes, switching actions, and other transients occurring so that in a strict mathematical sense most of the variables are varying with the time.
