REGULATOR OF A TRANSMISSION LINE THAT INCLUDES A CONTINUOUS CONTROLLED VOLTAGE SOURCE, SENSITIVE TO AN ACTIVE POWER DEMAND AS WELL AS A REACTIVE POWER DEMAND.

摘要

A TRANSMISSION LINE POWER CONTROLLER (50) IS PRESENTED TO CONTROL THE ELECTRIC POWER FLOW IN AN ALTERNATE CURRENT THREE-PHASE TRANSMISSION SYSTEM (34). THE POWER LINE CONTROLLER (50) INCLUDES A PARALLEL INVESTOR (22) CONNECTED TO A SERIAL INVESTOR (24) THROUGH A LINK (26). THE PARALLEL INVESTOR (22) IS CONNECTED IN DERIVATION TO THE TRANSMISSION SYSTEM (34) THROUGH A DERIVATIVE TRANSFORMER (36). THE SERIAL INVESTOR (24) IS IN SERIAL CONNECTION WITH THE TRANSMISSION SYSTEM THROUGH A SERIAL TRANSFORM (38). A TRANSMISSION LINE POWER CONTROL CIRCUIT (52) IS USED TO SPECIFY A REAL DESIRED POWER DEMAND AND A REACTIVE POWER DEMAND FOR THE TRANSMISSION SYSTEM (34). THE POWER CONTROL CIRCUIT (52) PROCESSES THIS INFORMATION TOGETHER WITH A TRANSMISSION LINE VOLTAGE VECTOR AND A TRANSMISSION LINE CURRENT VECTOR TO PRODUCE A POWER SUPPLY SIGNAL REFERENCE SIGNAL THAT APPLIES TO THE SERIAL INVESTOR (24) . IN RESPONSE TO THE TENSION SOURCE REFERENCE SIGNAL, THE SERIAL INVESTOR PRODUCES A VOLTAGE VECTOR INJECTED TO THE TRANSMISSION SYSTEM (34). THE INJECTED VOLTAGE VECTOR FORCES THE TRANSMISSION LINE CURRENT VECTOR UP TO A DESIRED VALUE THAT CORRESPECTS WITH THE SPECIFIED REAL POWER AND THE REACTIVE POWER DEMAND. IN THIS FORM, THE REAL DESIRED POWER AND THE REACTIVE POWER FLOW ON THE TRANSMISSION LINE (34) ARE RAPIDLY ACHIEVED.
