DISTRIBUTION SYSTEM INFORMATION SUPERVISORY SYSTEM AND SYSTEM INFORMATION SUPERVISORY SYSTEM

摘要

PPROBLEM TO BE SOLVED: To provide a distribution system information supervisory system which establishes a control algorithm for adjusting the voltage of a distribution system. PSOLUTION: The distribution system information supervisory system includes transformers LRT, SVR with an on-load tap changer installed in a distribution transforming station or on the way of a distribution line and connected to the distribution line, reactive power regulation devices DG, DES, SVC and STATCOM connected to the distribution line, and a distribution system information supervisory post having functions of collecting information of tap position of each device or reactive power and voltage and information of voltages of respective nodes of a high voltage distribution line and calculating process. The distribution system information supervisory system transmits the tap position determined in this distribution system information supervisor post to the transformers LRT, SVR with the on-load tap changer and transmits the command of the reactive power determined in the distribution system information supervisory post to the respective reactive power regulation devices.
