【正文】 wer, the regulation system adjusted according to the changes in the output power of the pitch angle size, so that the output power of the generator is maintained at the rated power. The disadvantage is that the more plex structure, a relatively high failure rate. 4 pitch classification Variable pitch unified pitch and independent pitch system in accordance with its work can be divided into two kinds of ways Unified variable pitch control that crew all blades by an executive agency drive, or drive three implementing agencies, the blade pitch angle changes. The torque of the hydraulic system, unified in a large wind turbine pitch distance is generally hydraulically. Independent variable pitch mode, each blade by the independent pitch actuator driver, if one pitch implementation of structural failure, and the other two blades can still adjust the blade pitch angle, the power control, unified pitch implementation of structural failure, only a maintenance shutdown。 during operation, when the output power is less than the rated power, the pitch angle to maintain the same, does not make any adjustment in the 0 176。, and then adjusted to 0 176。 6 主要技術(shù)性能指標(biāo) 伺服電機(jī) 額定轉(zhuǎn)速 2500 rpm 額定輸出電流 17A 額定轉(zhuǎn)矩 Nm 電源電壓 三相 AC380V 絕緣等級(jí) F 級(jí) 冷卻方式 自然冷卻 防 護(hù)等級(jí) IP64 環(huán)境溫度 － 25℃～＋ 40℃ 制動(dòng)裝置 選件 編碼器 絕對(duì)值位置編碼器 伺服驅(qū)動(dòng)系統(tǒng) 額定輸出功率 額定輸出電流 24A 額定輸出電壓 3 0400V(AC) 輸入電壓 3 AC380V(－ 25％～＋ 10％ ) 過載能力 43A/30 秒 冷卻方式 散熱器外置自然冷卻 防護(hù)等級(jí) IP24 或更高 環(huán)境溫度 － 25℃～＋ 40℃ 制動(dòng)電阻 外加 配置現(xiàn)場總線 CAN 總線 保護(hù)功能 電機(jī)三相短路保護(hù)﹑過載保護(hù)﹑電源過壓保護(hù)等 5 外文原文 1 fan pitch System Overview wind turbine control system hardware were installed in three different parts The cabin control, installed inside the cabin. Ground control, mounted on the bottom of the tower. Pitch control, internally mounted on the hub. manmachine interface The touch screen displays the operational status and parameters of the fan, or to start or stop the fan. wind turbine the four control way Constant speed given pitch control The generator is directly connected to the constant frequency of the grid, theaerodynamic control is not performed when the power generation. constant speed variable pitch control The generator is directly connected to the constant frequency of the power grid, power is used to adjust the pitch control in high winds. variable speed and pitch control The inverter of the generator and grid de
