Should the microprocessor based control system sense that the mains input is out of tolerance due to imbalance, voltage sags, harmonic distortion or flicker variations the IGBT based inverter will inject a correcting voltage via the re-injection transformer. Should a net average boost in output voltage be required the inverter will draw power through its rectifier supply. 交流临界载荷通过浇注变压器提供。如果基于控制系统的微处理器发觉电源输入功率由于不平衡、电压降、谐波或闪变超出了偏差，逆变器的IGBT通过串接变压器投入一个校正电压。如果电网上的平均值高于所需的输出电压，逆变器将通过整流器转移能量。Regenerativeoptions are available for the continuous correction of 3 phase over-voltage or a regenerative load through the use of a bi-directional regenerative rectifier that allows full control of output voltageeven under load power regeneration into the utility supply. (R version models). 此类产品利用双向整流器连续校正3相过电压或负载产生的过电压。双向整流器（可控制负载产生的能量流向电网）Overload过载In the event of an inverter overload the static switch will short the secondary of the re-injection transformer (inverter side) effectively bypassing the system and providing a raw mains supply to the output without interruption. Once the overload condition has been cleared the system shall automatically return to normal inverter based operation, again without interruption.在逆变器过载的情况下，静态开关有效短接浇注变压器的二次侧以避开系统同时不间断的为输出提供一个备用电源。一旦超载现象清除，系统会自动返回到正常的逆变器操作状态而没有中断。Maintenance Bypass维修旁路If for any reason the inverter or static bypass has to be taken out of service for maintenance or repair, the AVC shall be provided with an internal maintenance bypass switch. When used in conjunction with the static bypass switch the system can be switched in and out of manual bypass without any interruption to the connected load.如果逆变器或静态旁路需要停止运行以便检修，AVC拥有一个内部检修旁路开关。当结合使用静态旁路开关时，系统可以手动切换至旁路而不需中断链接负载。2.5 Performance性能2.5.1 Voltage Regulation电压调节The AVC shall regulate the output voltage to maintain a regulated nominal supply for the load. The maximum full level of correction shall be defined for each model. For example a 15% correction unit will provide complete correction for up to 15% mains reductions whereas a 30% model will extend complete correction to 30%. Should the mains voltage drop below the maximum level of complete correction the system will continue to operate providing the rated voltage boost but with the load voltage dropping below nominal.AVC调节输出电压持续供给负荷。对于每一套装置来说，最大满校正水平将会精确计算。例如：一个校正15的装置最大可校正至15的电压降。然而一个30的设备的最大校正值可扩展至30。有可能母线电压降到最大校正值以下，系统会继续提供额定电压，但是负载电压低于额定值。For optional R version models the AVC units can also regulate for over voltage conditions up to a maximum level as indicated in the model specification. The output mains voltage will be held constant at nominal until the regenerative power capacity of the rectifier is exceeded. With the AVC running at rated kVA capacity, at 0.8 power factor, the maximum overvoltage will be as shown in the model specification. The over voltage correction capacity will increase in inverse proportion to the load power level up to a maximum correction capability equal to the sag correction capability of the unit.对于可选的R型装置来说，像设备说明书里指出的那样，AVC装置同样可以最大程度的调节过电压。输出电压将保持在额定值直到超过逆变器产生的容量为止。当AVC在额定容量下的运行，功率因数0.8的情况下，在设备说明书中，同样指明了最大过电压。过电压校正容量会增长至最大的校正容量等同于装置的电压降校正容量，与负载功率相反。Overload Protection过载保护The AVC shall continue to operate under inverter control for temporary current overload conditions of up to 150% of the per phase system rating when operating under zero voltage correction conditions. Should the AVC be providing voltage correction the temporary and continuous load ratings of the AVC system shall be reduced by an amount proportional to the level of correction at the time of the overload. E.g. IF the AVC is not correcting at all it will provide 150% overload, if it is correcting a voltage of 20% sag then its overload is reduced to 120%. Should the AVC loading levels exceed the maximum inverter ratings or the timed overload level be exceeded the AVC system will switch to static bypass mode. NO storage mechanism is allowed to be used to maintain overloads or for voltage correction.在每相超负荷150的情况下，逆变器会控制AVC在0电压校正的状态下短时间持续运行。如果AVC提供电压校正，AVC系统的暂态运行时间和连续载荷在超负荷的同时会按照校正水平的比例降低。例如：如果在超载150的情况下，AVC根本不校正，如果它校正了20的电压降，则它的超载将减少至120。如果AVC负载水平超过了逆变器容量的最大值或者超过了被设定的过载水平，AVC将切换至静态旁路模式。任何储能途径都不允许被用来保持过载或电压校正。Static Switch静态开关The electronic switch shall be a naturally commutated, fully rated, high-speed solid-state transfer device. Operation of the static transfer switch will effectively connect the protected load directly onto the input mains supply. Transfer to and from static bypass condition shall occur with no interruption to the load.电子开关是一个自然整流的、完全额定的、快速的固态转换开关。静态转换开关的运行可有效的链接需要被保护的负载和输入电源。转换至静态旁路状态或从静态旁路状态转换时，负载无中断。Uninterrupted transfers to bypass through static switch operation will be immediately initiated by:以下现象会立刻启动转换开关运行，快速切换至旁路。q Output overload输出超载q DC voltage out of limits直流电压超限q Inverter failure逆变器故障q Over-temperature超温The AVC system can be transferred to static switch operation manually by depressing for a minimum of 2 seconds the red inverter off control key on the inverter keyboard. The system can then be transferred back to normal inverter operation by depressing the green inverter on key.在至少2秒的时间内，摁下逆变器键盘上的红色开关控制键，AVC可以手动转换至静态旁路运行状态。摁下逆变器绿色键，系统可以转换至正常的逆变器运行状态。Should a mains failure occur the AVC system will automatically re-power following mains restoration and return to operation in the system operating state prior to mains failure.如果总线发生故障,AVC系统会随着总线的修复自动重启并恢复到总线故障发生之前的运行状态。2.6 Specifications规格2.6.1 RATING功率 Rating (kVA) 功率（kVA） As specified per model, up to 60MVA根据不同的型号，可高达60MVA 2.6.2 SUPPLY INPUT电源输入 Nominal input voltage (V) 208V, 480 or 600V 3 ph (380-400V & 690V and up to 36kV options available) 额定输入电压（V） 208V，3相480或600V（380400V和690V，最高可达36KV可供选择）Nominal frequency (Hz) 50/60 selectable额定频率（Hz） 50/60 可选2.6.3 Efficiency 效率 Efficiency of system (= power out / power in):系统效率=（输出功率/输入功率） Half load (%) 99.0 半载（ ） Full load (%) 98.8 满负荷（ ）2.6.4 AVC OUTPUT AVC的输出Nominal voltage (V) 208V, 480 or 600V 3 ph (380-400V & 690V and up to 36kV options available) 额定电压（ V ） 208V，3相480或600V（380400V和690V，最高可达36KV可供选择）2.6.5 Correction (%) As specified per model, 30% or 40% (max correction for sag)校正（ ） 根据不同的型号， 30 或40 （最大值校正电压降）2.6.6 Dynamic Response动态响应Response (to sag event) 1 ms to respond and 6-8 ms, will be the time taken to restore a 30% variation to within 2%响应（对于电压降） 响应 1毫秒，经过68ms从30 校正至2 以内2.6.7 RESERVE STATIC SWITCH预留静态开关 Nominal Power (kVA) AVC rating x 1.1 额定功率（千伏安） AVC容量的1.1倍 Maximum overload capacity: 最大负荷能力： For 10 minutes (%) 10分钟 125 For 1 minute (%) 1分钟150 For 600 milliseconds (%) 600毫秒700(in static bypass) 静态旁路 For 100 milliseconds (%) 100毫秒1000(in static bypass) 静态旁路 Transfer time: 转换时间： Inverter to static bypass (ms) 0.5ms逆变器到静态旁路（毫秒） Static bypass to inverter (ms) 0.5ms 静态旁路到逆变器（ MS ） Cooling Forced ventilation 冷却 自然风冷 ENVIRONMENTAL环境 Temperature: 温度 Operating (deg C) 0-40 degrees C.操作系统（摄氏度） 0-40 Elevation without derating 3300ft(1000m) (-1.2% Pn every 100m above 1000m) 不降低功率的海拔 三千三百英尺（ 1000 ） （ 1000米以上每升高100米功效降低1.2）2.7 Operator Interface Module操作界面模块2.7.1 General概述The AVC shall incorporate the necessary controls, instruments and indicators to allow the operator to monitor the system status and performance, as well as take any appropriate action.AVC包含必须的控制器，仪器和指示器，以便操作员监测系统的状况和性能。2.7.2 Keyboard and Display键盘和显示屏An 80 character (4 line by 20 character) illuminated Liquid Crystal Display (LCD) shall be provided to enable the operating parameters of the AVC to be monitored and adjusted.
