The Complex Generating System, which uses parallel connection of Photovoltaic System and other generating systems, is divided into 2 types. One is AC parallel system and the other is DC parallel system.
AC parallel system consists of alternating generator (diesel generator) and direct generator (wind power or solar power generator), which are connected through 2-way invertor so that the generated power can be transformed into AC power and finally covers the power load. In case it generates surplus electricity, the residual power is to be charged in batteries to raise the performance and the power balance.
This study is to explore the electric characteristics such as power voltage, and the change of power load when operating both Utility Interactive Photovoltaic System and Diesel AC Generator connected to the system in alternating current and with influx of residual power from the Photovoltaic System.
As a result of Road Variation and supplying 10.7 ㎾, 13.5 ㎾ of residual power, it has been found that Synchronous Generator takes the power input only as reactive power, because it was electrically stable with high voltage of 221[㎾] even when power factor was -0.901. Thus, load share of Revolving Field Type Synchronous Generator reduces according to the supply of Photovoltaic System to the load power. In this experiment, 200[㎾] of Synchronous Generator and 40[㎾] of Photovoltaic System were operated in parallel. The load share was 20% in maximum, and fuel was saved.
Utility Interactive Photovoltaic System and Diesel Engine Revolving Field Type Synchronous Generator are usually implemented in remote regions like islands and mountains where KEPCO Distribution network does not reach. This thesis is to present effective ways of control for A.C. parallel operation by researching electrical, mechanical characteristics of it.
