我公司在APF 設計過程中，緊跟電力電子設備的發(fā)展趨勢，廣泛借鑒各行業(yè)相關(guān)設備的優(yōu)點，將這些技術(shù)特點整合而成新APF，從成本、性能、交貨速度、可適拉性、可擴展性各方面，都在國內(nèi)同行業(yè)中具有一定優(yōu)勢。
◇ 模塊化抽屜式功率模塊
目前市場上有源電力濾波柜分兩種拓撲結(jié)構(gòu)：一種是一體式設計，機柜由多少個單一獨立的元器件構(gòu)成，如三相各三個IGBT，三個風扇，三個熔斷器，三個避雷器等等，屬于比較老式的設計，這種結(jié)構(gòu)的缺點是當有一個元器件壞了，將會導致整機停止工作，因此其可靠性不高；另一種是模塊化設計，是電力電子產(chǎn)品的發(fā)展方向機柜由多個功率模塊組合而成，每個模塊完全一樣，都能獨立運行，多個模塊并聯(lián)起來共同運行，當任一模塊出現(xiàn)故障時，其他模塊自動平均分擔負荷繼續(xù)正常運行。
◇ 強大的綜合電能質(zhì)量治理功能
設備可以同時實現(xiàn)以下功能，用戶可以通過觸摸屏的人機界面，選擇優(yōu)先級、選擇同時實現(xiàn)。
In the process of APF design, our company follows the development trend of power electronic equipment, widely draws on the advantages of related equipment in various industries, and integrates these technical features into the new APF, which has certain advantages in the same industry in China in terms of cost, performance, delivery speed, adaptability and expandability.
◇ Modular drawer type power module
At present, the active power filter cabinet in the market is divided into two topologies: one is the one-piece design, the cabinet is composed of how many single independent components, such as three IGBTs in each of the three phases, three fans, three fuses, three surge arresters, etc., which is a relatively old design, the disadvantage of this structure is that when one component is broken, it will lead to the whole machine stop working, so its reliability is not high; the other is The other is modular design, which is the development direction of power electronic products. The cabinet is made up of multiple power modules, each module is exactly the same and can run independently, multiple modules are connected in parallel to run together, and when any module fails, other modules automatically share the load on average to continue normal operation.
◇ Powerful comprehensive power quality management function
The equipment can realize the following functions at the same time, and users can select the priority and choose to realize them at the same time through the human-machine interface of touch screen.
有源速波：濾除50 次以內(nèi)諧波
電壓偏離：雙向補償電壓升高與電壓跌落
固定電流：發(fā)出指定的任意電流
用戶可以實時觀測到電壓、電流、諧波、有功、無功、功率因數(shù)、故障記錄等所有電量參數(shù)。
起到電能質(zhì)量監(jiān)測的作用。同時，對于本機各模塊的工作狀態(tài)、當前溫度、故障記錄等，都可以通過人機界面實時查看。
◇ 高可靠性并機方式：同一個控制器集中控制，模塊之間無環(huán)流
AB-APF 可以實現(xiàn)4 臺裝置并聯(lián)且只使用一個控制器集中控制，每個功率模塊均流輸出。模塊之間無環(huán)流，提高了裝置的可靠性。
Active speed wave: filter out harmonics up to 50th
Voltage deviation: bi-directional compensation of voltage rise and voltage dip
Fixed current: issue specified arbitrary current
Users can observe all power parameters such as voltage, current, harmonics, active power, reactive power, power factor, fault records, etc. in real time.
It plays the role of power quality monitoring. At the same time, the working status, current temperature and fault records of each module of the machine can be viewed in real time through the man-machine interface.
◇ Highly reliable parallel mode: Centralized control by the same controller, no loop current between modules
AB-APF can realize the parallel connection of 4 units and use only one controller to control them centrally, with each power module outputting evenly. There is no loop current between modules, which improves the reliability of the device.

◇ 三電平結(jié)構(gòu)：輸出電流平滑，裝置損耗低
主電路采用三電平全橋拓撲三電平結(jié)構(gòu)，輸出電流波形平滑，同時使直流母線電壓和開關(guān)器件的開關(guān)頻率僅有傳統(tǒng)兩電平有源濾波器的1/2，大大降低了開關(guān)器件的損耗。
◇ Three-level structure: smooth output current, low device loss
The main circuit adopts three-level full-bridge topology three-level structure, with smooth output current waveform, while making the DC bus voltage and switching frequency of the switching device only 1/2 of the traditional two-level active filter, which greatly reduces the loss of the switching device.
◇ 自適應控制算法：適應任何系統(tǒng)阻抗變化
控制系統(tǒng)能夠根據(jù)輸入信號自動調(diào)整控制參數(shù)，優(yōu)化補償性能，并能適應任何系統(tǒng)阻抗變化，裝置不會與系統(tǒng)發(fā)生諧振。
◇ 各次諧波電流輸出可限幅：可與無源濾波器配合濾同一次諧波
因為現(xiàn)場可能存在復雜的應用環(huán)境，比如電網(wǎng)本身是個弱電網(wǎng)，電網(wǎng)的阻抗發(fā)生變化，電容器變頻器等多種類型的設備同時并聯(lián)在電網(wǎng)中，導致設備間發(fā)生諧振。因此本設備從2~50 次諧波都可設置最大輸出值，以防止發(fā)生諧振。
◇ Adaptive control algorithm: adapt to any system impedance change
The control system can automatically adjust the control parameters according to the input signal to optimize the compensation performance, and can adapt to any system impedance changes, and the device will not resonate with the system.
◇ The output of each harmonic current can be limited: it can cooperate with passive filter to filter the same primary harmonic
Because the site may have complex application environment, such as the grid itself is a weak grid, the impedance of the grid changes, capacitors inverters and other types of equipment connected in parallel in the grid at the same time, resulting in resonance between equipment. Therefore, this equipment can set the maximum output value from the 2nd to the 50th harmonic to prevent resonance from occurring.
