Title:
EQUIPMENT PLANNING ASSISTANCE DEVICE AND EQUIPMENT PLANNING ASSISTANCE METHOD FOR POWER DISTRIBUTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2016/143689
Kind Code:
A1
Abstract:
Provided are an equipment planning assistance device and an equipment planning assistance method for a power distribution system, said device and method setting an operation setting value, which makes a hunting frequency less than or equal to a predetermined value, to a voltage adjustment device that adjusts a tap position when the time integral value of the voltage deviated from a predetermined secondary side voltage exceeds a predetermined value (operation setting value). The equipment planning assistance device is a device for assisting equipment planning of a power distribution system in which a plurality of voltage adjustment devices are disposed in series, said voltage adjustment devices adjusting the tap of a transformer with a tap when the integral value of the voltage deviated from the allowable range of the secondary side voltage of the transformer with a tap exceeds the operation setting value. The equipment planning assistance device is provided with: a setting database provided with a plurality of the combinations of the operation setting values of the respective voltage adjustment devices on the upstream and downstream sides and storing a hunting frequency representing a series of operations in which each step voltage regulator repeats a tap adjustment when having each of the combinations of the operation setting values; an operation setting-value setting processing unit for calculating a combination of the operation setting values on the basis of a combination of the operation setting values read from the setting database and the corresponding hunting frequency; and a display unit for displaying the operation setting values calculated by the operation setting-value setting processing unit and the hunting frequency.
