FKJ-B型(PWM)离网风光互补/风力发电机控制器20KW-30KW

pwm型产品特性

◆本产品依照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pwm恒压功率范围时，三相卸荷立即自动启动，保证风力发电整套系统安全运行。

◆在蓄电池脱节、损坏情况下，三相卸荷自动启动。防止风力发电机空转、飞车事故发生。

◆ pwm控制。在大风、强风情况下，保证风力发电机对蓄电池恒压、恒流充电。

◆蓄电池防反接保护，蓄电池防脱节保护，蓄电池防损坏保护。

◆蓄电池过充保护。当蓄电池充满时（蓄电池电压达到额定电压125%），控制器将自动三相卸荷，停止对蓄电池充电。

◆蓄电池自动恢复充电功能。当蓄电池电压降至额定电压108%时，三相卸荷器停止卸荷，自动恢复对蓄电池充电。

◆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。风力发电机、太阳能电池板、蓄电池、控制器工作状态一目了然。

◆电流表、电压表指示。指示蓄电池充电电流及蓄电池电压。

◆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。

pwm model product characteristics

◆the product can be manufactured in accordance with either jb/t6939.1-2004 industrial standard, gb/t 19115.1-2003 national standard or users’ technical requirements.

◆adopt two sets of control systems, pwm constant pressure system and three-phase load discharging system.

◆pwm constant pressure control is 120% of the rated power of the wind turbine generator. in case of exceeding the scope of pwm constant pressure power, the three-phase load discharging will automatically start immediately to ensure safe operation of the overall wind turbine generation system.

◆under the circumstances of decoupling and damage of the battery, the three-phase load discharging will automatically start to avoid the idle run of the wind turbine generator and the occurrence of runaway accident.

◆pwm control: under the conditions of strong or super-strong wind, ensure battery charged by the wind turbine generator under constant voltage and current.

◆it hasreverse connection, anti-decoupling and damage-resisting protection of the battery.

◆over-charging protection of the battery:when the battery is full (the battery pressure reaching 125% of the rated pressure), the controller will automatically carry out three-phase load discharging to stop charging battery.

◆auto recovery of battery charging: when the battery pressure reduces to 108% of the rated pressure, the three-phase load discharger will stop load discharging to automatically recover battery charging.

◆in line with the category of the wind turbine generator, the controller can be additionally equipped with mechanical yawing, swing-tai, mechanical or hydraulic, pneumatic, magnetic and other brake functions.

◆the inside of the controller is equipped with lightening protection device.contain the transit over voltage penetrating into the wind turbine generator within the voltage scope bearable to the equipment or system or conduct the strong lightening current into the earth to avoid equipment damage posed by lightening impact.

◆led status indication: clearly present the working statusof the wind turbine generator, solar panel, battery and controller.

◆ammeter and voltmeter indication: indicate the charging current and voltage of the battery.

◆the controller is equipped with manual three-phase load discharging switch; the user may use it according to actual circumstances. when using this switch, the wind turbine generator will forcibly carry out three-phase load discharging.
