FKJ-GT(并网)型产品特性
◆本产品参照JB/T6939.1-2004号行业标准,GB/T19115.1-2003号国家标准生产,也可根据用户技
术要求生产。
◆采用两套控制系统,PWM恒压系统+三相卸荷系统。
◆ PWM恒压控制是风力发电机额定功率的120%。当超出PWM恒压功率范围时,三相卸荷立即启动运行,运行10-20分钟停止三相卸荷,风力发电机恢复供电,保证风力发电整套系统安全运行。
◆在大风、强风情况下,控制器恒压输出,保证逆变器正常工作。
◆在并网逆变器掉线情况下,控制器恒压输出,等待逆变器恢复工作。
◆当电网停电时,控制器三相卸荷自动启动,逆变器停止向电网输出。待网电恢复供电时,控制器停止三相卸荷,逆变器恢复供电。
◆控制器根据风力发电机的种类,可增加机械偏航控制、机械折尾控制、机械或液压、气压、电磁,等多种制动控制功能。
◆控制器内部设有防雷器。把窜入风力发电机电力线的瞬时过电压限制在设备或系统所能承受的电压范围内,或将强大的雷电流泄流入地,保护设备不受雷电冲击而损坏。
◆ LED灯状态指示。前面板有风力发电机指示、卸荷指示、三相卸荷延时指示、欠压指示、网电指示,及直流输出电压指示。◆电压表指示。指示控制器DC输出电压。◆控制器具有急停开关,遇紧急情况时,按下前面板急停按钮,控制器全部电源切断,风力发电机立即三相卸荷。
◆控制器具有手动三相卸荷开关,用户可根据情况使用。使用此开关,风力发电机将强制性三相卸荷。
FKJ-GT(Grid-tie)model Product Characteristics
◆The product is manufactured according the JB/T6939.1-2004 industrial standard and GB/T 19115.1-2003 national standard also with users’ technical requirements.
◆Two sets of control systems:PWM constant voltage system and three-phase dump load system.
◆PWM constant voltage control is 120% of the rated power of the wind turbine. In case exceeding of PWM’s capacity, the three-phase dump load will automatically startimmediately. After 10-20 minutes, the three-phase dump load will stop and the wind turbine will re-start to resume power supply to ensure the safe running of the overall wind turbine generation system.
◆Under the strong or super-strong wind conditions, the controller can conduct constant voltage output to ensure the inverter safety running.
◆Under the condition of disconnected grid-connected inverter, the controller can conduct constant voltage output and wait for inverter resumption.
◆The three-phase dump load of the controller will automatically start and the inverter will stop grid output when the power grid is off. As soon as the grid power resuming, the controller stops three-phase dump load and the inverter will resume power supply.
◆For the different wind turbine generator type, the controller can be equipped with mechanical yawing,furled empennage,mechanical or hydraulic, pneumatic, electric magnetic and other brake functions.
◆The inside of the controller is equipped with surge arrester.Contain the over voltage into the wind turbine under the bearable voltage of the equipment or system. On another way, to conduct the strong lightening current into the earth directly to avoid any damage of equipment.
◆The below LED status indication can be found onthe front panel: indications of wind turbine, dump load, three-phase dump load delay time, under pressure, grid power and DC output voltage.◆Voltmeter indication: Indicate the controller DC output voltage.◆The controller is equipped with emergency stop switch; in case of emergency, press down the emergency stop button in the front panel to cut off all power supply of the controller and the wind turbine will immediately carry out three-phase dump load.
◆The controller is equipped with manual three-phase dump load switch. To using this switch, the wind turbine will carry out three-phase dump load forcibly.
