METHOD FOR FAST-ACTING CONTROL OF ACTIVE-POWER FLOW

摘要

FIELD: electricity. ^ SUBSTANCE: during regulation of active-power flow between power system parts connected with power line (1), unbalance of active power on shaft (11) of generating unit is monitored, active-power flow over line (1) is changed by adjusting phase angle between voltage vectors in its end-points on buses (2) and (3) by means of controlled phase-slue device (12) included in line (1). Limited time interval is allocated, within which unbalance of active power is compensated by means of transferring electric energy accumulator (7) into discharging or charging mode when there is deficiency or excess of active power respectively, and power balance is restored by corresponding changing power generated by unit. ^ EFFECT: higher speed of active power adjustment without lowering electric energy quality and power system stability margin. ^ 4 cl, 1 dwg
