simple, less calculating volume, only approximate results. Can give here some method used a whole lot more to determine the load calculations when planning and design of the power supply system.The method for calculating load cell used in the design of the power supply system as follows:II. The method for determining the load calculations:1. Method of determining the load calculations (PTTT) according to the capacity and needs of system: PTT = knc. Pđ Of which: knc: coefficient of demand, in the technical manual.Pđ: the capacity of the device.2. Method of determining PTTT according to the form of the extra loads and graph the average power:PTT = khd. PTBOf which:khd: form of extra load load graphs, look in the technical manual.PTB: average capacity of the device or group of devices, (KW) 3. The method determined by the average power and PTTT deviation of extra load graph from the average value:PTT = Ptb ± βσOf which: PTB: average capacity of the device or group of devices, (KW).σ: deviation of extra load graph from the average value.β: scattering coefficient of σ
