TAP CONTROL SYSTEM
Document Type and Number:
Japanese Patent JPS63231604
Kind Code:
A
Abstract:
PURPOSE:To improve the workability by providing an operation processing part of a centralized control apparatus with a tap operation number operating means and a comparing means. CONSTITUTION:An input signal is inputted to an operation processing part 50, and a number DELTAT of times of tap operation is obtained in a tap operation number operating means 51 in accordance with DELTAT=chi-PI (chi is the target tap position signal and PI is the current tap position signal and is always inputted). The obtained number DT is compared with a comparison value by a comparing means 52, and a tap raising or lowering command is converted to a prescribed transmission format in accordance with the comparison result and is sent to a remote information transmission equipment 4. Thus, the tap operation is automatized and the tap value is arbitrarily designated at the time of completing the parallel driving operation of transformers.
