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 systems 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泰国5kwh并网光伏发电系统性能 摘要：本文总结了前8个月的监测PHA的邦光伏发电项目，一个500 kWp的太阳能光伏试验厂在泰国湄宏顺省。这在泰国西北偏远地区的地方电网是在其能力非常有限，不能放大。它已在2004年3月20日开始运作，由产电量400 VAC，22千伏中压电网组成。该系统由光伏阵列1680模块（140字符串，12个模块/串;300瓦/模块），电源空调机组和电池的转换系统。在这个系统的运作的第一个8个月，约383274千瓦时的电由光伏发电系统产生。 “每天产生的电力生产平均为1695.9千瓦时，范围由1452.3至2042.3千瓦时。光伏阵列系统的效率从9至12不等。的效率功率调节单元（PCU）从92至98范围内。最终的收益率（YF）的范围从2.91到3.98 H / D的性能比（PR）的范围从0.7至0.9关键词：太阳能发电系统;性能;电网连接系统I IntroductionMae 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 provinces 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 about20004000 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 constrainsrequire careful planning of the electricity supply in Mae Hong Son.EGAT, the organization responsible for supply and generation of electricity in Thailand, encourages the study, exploration and planning for use of renewable energy in this province. It has initiated a pilot PV project in Mae Hong Son, the 500 kW Pha Bong photovoltaic generation. The project has three objectives; to increase power supply, to decrease consumption of diesel fuel during daylight hours and finally to encourage a national strategy in the production photovoltaic cell and accessories. Work on the Pha Bong photovoltaic generation was commenced on 11 February 2003. The system first began to supply the first electricity to 22 kV grid system of Provincial Electricity authority (PEA) on 20 March 2004 and has been completely operational since 24 March 2004. The project was handed over to EGAT on the 9 April 2004. However, far the performance of their paper data was collected from 24 March 2004 when the project was completely operational and being fully monitored until 31 October 2004 13. This paper presents an evaluation of the performance of system during the first eight months of operation. The performance of the components of the system (PV arrays, power condition unit) is analyzed, and finally the performance of the whole system is investigated. A later paper will review information about the performance of the battery and converter system used to improve the reliable of the system and its connection to the grid.II System component, design and featur
