초록 ▼

Controlling a customer voltage and VAR flow in a power transmission and distribution system includes measuring first voltages in a power line directed to a first location related to customers. Both the customer voltage and the VAR flow for the network is determined in relation to the number of capacitors associated with the first location which are switched in or out of the network. The measured voltages are communicated to a voltage control. Voltage deviations of the measured first voltage are determined relative to a predetermined voltage range intended to be present at the first locations. Switching the capacitor means into or out of the network is determined by the voltage control in accordance with a voltage rise table. A VAR flow controller is responsive to the voltage at the first locations, the effect of the VAR generation by the capacitors and the change of VAR generation by the capacitor. A decrease in voltage at the customers saves energy use. A decrease in the VAR generated upstream of the customer results in greater efficiency of energy generation.

대표청구항 ▼

A method for controlling voltage in a power distribution network including power lines for distributing power at a lower voltage and at a higher voltage, power being distributed at the lower voltage to multiple lower-voltage locations, the network including, at the higher voltage, capacitor means and switch means for selectively switching the capacitor means into or out of the network, the method comprising the steps of: (a) measuring the voltage at one or more lower-voltage location, (b) ascertaining the deviation, if any, of the measured voltage from a predetermined voltage range intended to be present at the lower-voltage location, (c) determining whether switching the capacitor means into or out of the network changes the voltage deviation to bring the voltage at the measured lower-voltage location within the predetermined voltage range, and (d) selectively transmitting a signal to the switch means for switching the capacitor means into or out of operation in the network to effect a change in the voltage at the measured lower-voltage location.
