Abstract: This paper summarizes the first eight months of monitoring of the PHA BONG photovoltaic Generation project, a 500 kWp photovoltaic pilot plant, in Mae Hong Son province, Thailand.The local grid in this remote area in the North West of Thailand is very limited in its capacity and cannot be enlarged. It has been in operation since 20 March 2004 by feeding into 400 VAC, 22 kV medium voltage grid. The system consist of a photovoltaic array 1680 modules (140 strings,12 modules/string; 300 W/module), power conditioning units and battery converter system. During the first eight months of this system’s operation, the PV system generated about 383,274 kWh. The average of generating electricity production per day was 1695.9 kWh. It ranged from 1452.3 to 2042.3 kWh. The efficiency of the PV array system ranged from 9 to 12%. The efficiency of the power conditioning units (PCU) is in the range from 92 to 98%. The final yield (YF) ranged from 2.91to 3.98 h/d and the performance ratio (PR) range from 0.7 to 0.9.

Keywords:  Solar power system; Performance; Grid connected system

I Introduction
Mae Hong Son province is situated in North Western of Thailand on the bounder with Myanmar. The Province has only 22 kV distribution lines which take power from Chiang Mai substation and passes through trees and hills for 250 km. The supply often fails, as trees touch the conductors. The main electricity supply of Mae Hong Son, in the province’s amphora mange zone, has three sources, The Pha Bong dam (PB-Dam;1850 kW), The Mae Sa Yha Dam (MSY-Dam; 2!3375 kW), and Mae Hong Son Diesel generator (MHS-Diesel; 31000 kW,3!1250 kW). The total generation capacity of this installation is about 14,350 kW. Normally power generation from dams is able to supply electricity about eight months per year, and is shut down in summer and winter seasons. The PB-Dam can supply about 460 kW and the MSY-Dam can supply about2000–4000 kW. Generation capacity depends on the season as the dams were not built for storage. The MHS-Diesel generator can only supply about 6000 kW. The policy of the Electricity Generating Authority of Thailand (EGAT) gives first priority to generation from the dams, a renewable energy resource. If the supply from dams is insufficient, diesel generation used to supplement the supply. In this way the use of costly diesel oil is minimized. The peak demand on 10 October 2004 at 19.30 p.m. was about 4660 kW and the maximum day-load at 15.00 p.m. was about 3030 kW. The supply constrains(责任编辑:英语论文代写)
