Optimal capacitor placement, considering power system loss reduction, voltage profile improvement, line reactive power decrease and power factor correction, is of particular importance in power system planning and control. The distribution system operator calculates the optimal place, number and capacity of capacitors based on two major purposes: active power loss reduction and return on invest...

Due to the low transmission capacity margin of overhead conductors ACSR type in existing grid structure, large-scale connection new energy is greatly limited. However, 60% IACS heat-resistant have conductivity and high power loss process. Therefore, 61. 5% aluminum alloy with are developed for line expansion reconstruction. The feasibility stranded conductor analyzed combination example urban t...

A universal design method for synthesis problems of mechanisms that realize the approximate straight-line trajectory is presented in this paper. First, given expected straight line and prescribed fixed pivots, a general mathematics model with angles as parameters to determine initial position two side links established, through which all infinite possible are obtained. Then, kinematic constrain...
