Embodiment Construction

[0016] Embodiments of the present invention will be described in more detail below with reference to the accompanying drawings.

[0017] figure 2 is a block diagram showing the overall structure of a hybrid power generation system according to an embodiment of the present invention; image 3 A schematic diagram of the detailed structure of the hybrid power generation system according to this embodiment of the present invention is not shown.

[0018] see figure 2 , the hybrid power generation system includes a generator 30 , a power transfer switch (powertransfer switch) 40 and a generator controller 50 . The generator 30 can be driven to generate electricity without auxiliary equipment, and outputs self-generated electric power. The generator controller 40 controls the generator 30 or the power source 20 supplying standard commercial power to selectively cause one of the generator 30 and the power source 20 to supply power to the load 10 according to the amount of generat...

Abstract

The present invention relates to a hybrid generation system and a control method thereof. The hybrid generation system can maximize operation efficiency of a generator by selectively supplying normal utility power or power, which is generated by the generator, based on a power level supplied to a load. A hybrid generation system includes a generator and a generator controller. The generator generates power, and the generator controller performs a control activity to supply one of the normal utility power and the generated power to the load. The selective supply of the normal utility power or the generated power can maximize efficiency of the generator and as a result, a power consumption level of the hybrid generation system can be decreased, thereby reducing related costs.

Description

technical field [0001] The present invention relates to a hybrid power generation system and its control method, in particular to such a hybrid power generation system and its control method: the system selectively supplies standard mains power and generators to the load according to the power supplied to the load One of the self-generated electricity. Background technique [0002] Electricity is often required to drive electrical appliances and equipment for domestic or industrial use. Typically, these household or industrial appliances and devices obtain the necessary power by supplying a power supply of standard mains electricity provided by a power station such as Korea Electric Power Company. However, there are often situations where the standard commercial power provided externally is not enough to provide power for all the loads in the factory, and therefore, it is often necessary to prepare a separate self-generation system. [0003] figure 1 is a schematic diagra...
