通過調節(jié)電源電壓就能夠滿足動態(tài)過程中轉速調節(jié)的要求。二是基于損耗模型的矢量節(jié)能優(yōu)化控制，與標量控制相比，矢量控制算法比較復雜，且對感應電機的軟硬件控制要求也比較高，隨著電機控制系統(tǒng)的軟硬件性能以及參數辨識技術的不斷提高，通過對鐵耗時矢量節(jié)能控制系統(tǒng)的優(yōu)化來實現(xiàn)電機節(jié)能運行的控制，滿足高動態(tài)性能的調速場合，如數控機床、電動機車等。由于感應電機在動態(tài)制動過程中會受到變頻器大電壓和電流的限制，可以通過轉速調節(jié)器的限幅控制來實現(xiàn)，可以設計如下控制方案：將矢量控制與節(jié)能控制有機結合在一起，通過磁鏈優(yōu)化控制來實現(xiàn)感應電機的節(jié)能控制，采用節(jié)能優(yōu)化后的磁鏈進行矢量控制，其效率會有一定的提升，特別是對轉速接近于額定轉速以及低負載轉矩的運行工況效率的提高。

腐蝕性氣體→主要是銅排、各器件的管腳會腐蝕如果現(xiàn)場的海拔標準高度超過1000m，變頻器運行有什么注意事項？現(xiàn)場的海拔標高過1000m時，請把負載率減少（因冷卻效果降低）。標準2000m：把負載電流下降到90％。3000m：把負載電流下降80％如果在安裝場所有振動，如何解決？基本上變頻器不允許振動，即使開始的時候沒問題，時間長了也會出現(xiàn)故障。如果沒有無振動的安裝場所，請采用防振膠墊。注意：一般規(guī)格表上的”振動”表示”運輸過程中的振動”并不是”使用時的振動”。變頻器的過電流保護及處理方法？A、過電流保護功能：變頻器中,過電流保護的對象主要指帶有突變性質的、電流的峰值超過了變頻器的容許值的情形。

By adjusting the power supply voltage, the requirements of speed regulation in the dynamic process can be met. Second, vector energy-saving optimization control based on loss model. Compared with scalar control, vector control algorithm is more complex and has higher requirements for induction motor hardware and software control. With the continuous improvement of hardware and software performance and parameter identification technology of motor control system, the control of motor energy-saving operation can be realized by optimizing the iron time consuming vector energy-saving control system. Meet the high dynamic performance of speed control occasions, such as CNC machine tools, electric locomotives, etc. Since the induction motor is limited by the high voltage and current of the inverter during dynamic braking, it can be realized by the limiting control of the speed regulator. The following control scheme can be designed: The vector control and energy saving control are organically combined, and the energy saving control of induction motor is realized through flux optimization control. The efficiency of vector control using the flux optimized after energy saving will be improved to a certain extent, especially for the operation condition with the speed close to the rated speed and low load torque.

Corrosive gas → Mainly copper bars, the pins of each device will corrode If the standard altitude of the site exceeds 1000m, what are the precautions for the operation of the inverter? When the elevation of the site exceeds 1000m, please reduce the load rate (due to the reduction of cooling effect). Standard 2000m: Reduce the load current to 90%. 3000m: Reduce the load current by 80% if there is vibration in the installation site, how to solve it? Basically, the frequency converter does not allow vibration, even if there is no problem at the beginning, there will be a failure for a long time. If there is no vibration-free installation site, use vibration-proof rubber pads. Note: The “vibration” on the general specification sheet means “vibration during transportation” and not “vibration during use”. Inverter overcurrent protection and treatment method? A. Overcurrent protection function: In the frequency converter, the object of overcurrent protection mainly refers to the situation with mutability and the peak value of current exceeds the allowable value of the frequency converter.
