MODIFICATION OF THE MASTER GENERATOR METHOD USED FOR FREQUENCY AND VOLTAGE CONTROL IN ISOLATED POWER SYSTEMS WITH PARALLEL OPERATING AC GENERATORS

Such methods as droop method, curve shifting method and master-slave were primarily developed for voltage frequency regulation in isolated power systems with synchronous generators. In modern induction generators, regulated dump loads, energy storage devices AC/DC AC/DC/AC converters, etc. are used addition to The investigation of new configurations is closely tied further development control load sharing the systems. article reviews simple-to-implement known parallel operated generators proposes a modification static var compensators, loads interface converters. system “Hydroelectric unit generator - hydroelectric an compensating capacitors transformer – AC local load" considered two techniques electric magnitude specified presented accordance statements proposed modified method. algorithm controller agreement speed master unit. functions assigned electronic PID maintain equal nominal value regulate active sharing. Verification algorithms was carried out. References 23, figures 5, table 1.
