LOCAL POWER SYSTEM AND A CONTROL METHOD THEREOF, CAPABLE OF IMPROVING THE EFFICIENCY OF GENERATING POWER

摘要

PURPOSE: A local power system and a control method thereof are provided to maintain the operation ratio of a binary power system as a relay for preventing a reverse power flow is not operated.;CONSTITUTION: A control method for a local power system comprises a power system(3), a power load(2), and a unit for preventing a reverse power flow. The power load is connected to a power generator. The unit for preventing a reverse power flow blocks the reverse power flow from the power generator to the local power system. The control method controls the quantity of electricity supplied to the power load by coping with the sate of the variable power load.;COPYRIGHT KIPO 2013;[Reference numerals] (12a) First unit for measuring generated power; (12b) Second unit for measuring generated power; (12c) Third unit for measuring generated power; (14) Unit for calculating a flow rate; (15) Pump control unit; (5) Relay for preventing reversed power flow; (AA, DD) Power supply system; (BB, EE) Electric power loads; (CC, FF, 2) External loads; (GG) Controller; (HH) Binary power generation system; (II) Power generator; (JJ) Hot water; (KK) Coolant; (LL) Evaporator; (MM) Expander; (NN) Condenser; (OO) Working fluid
