有源電力濾波器
有源電力濾波器-原理：
有源電力濾波器（APF，Active Power Filter）以並聯的方式接入電網，通過外部高精度採樣CT實時監測負載電流，將採集的信號轉換成數位訊號後，送至控制電路的諧波分離模組，該模組將基波成分分離，將諧波成分送至調節和監測模組。該模組會將採集到的系統諧波成分和IFTSINE 已發出的補償電流比較，然後通過PWM信號傳送給內部IGBT,控制逆變器產生一個和負載諧波電流大小相等，方向相反的諧波電流注入到電網中，達到濾波的目的。

● 快速回響能力 先進的算法使得本產品能夠在100us時間內計算出下一個開關頻率的輸出，故而回響速度不超過100us，對於變化較為頻繁的諧波能夠實行快速的補償。 Fast response ability: Advanced control can get the next PWM output in 100us, so IFTSINE can compensate the loads changing fast. ● 高度的可靠性 具有輸出過電流、直流側過電壓、直流側欠電壓、交流側過電流、交流側過電壓、IGBT死區保護以及IGBT綜合保護等多種保護功能，確保在系統或設備出現運行異常時，可靠地使設備退出運行或保護系統及設備。 High reliability: IFTSINE has output over-current, DC over-voltage and less-voltage, AV over- voltage and over-current, IGBT dead area protection, IGBT comprehensive protection and son on. The all can protect or exit device and system under an unusual situation. ● 大容量的補償能力 有源濾波器的補償能力受IGBT容量的限制，難以對大容量諧波進行補償，本產品做到不受限制地進行並櫃擴容，使得對大容量諧波的補償成為可能，並且大大降低了成本。 Large compensation ability: Filter compensation by IGBT capacity constraints, it is difficult to carry out the bulk of harmonic, IFTSINE is not unrestricted and expansion tank, leads to a large-capacity possible compensation of harmonic and dramatically lowered costs. ● 簡單的操作方法和結構 操作簡單，只需與負荷並聯入系統，無需進行其他的操作。內部結構簡潔，變流器為模組化結構，易於安裝和維護，接入系統後，無需人工干預即可正常運行。 Simple operation and structure: Only enter the system parallel with the load, and no carry on other operations. The internal structure is succinct and the converter is the modular structure, which is easy to install and the maintenance. After turning on the system, IFTSINE does not need the manual intervention to operation. ● 高性價比 全面國產化技術，控制器、變流器以及產品結構等方面具有自主的智慧財產權。 High cost performance: Localization technology, controllers, converters, and product structure are with independent intellectual property rights. ● 節能降耗能力 相比較無源濾波器而言，有源濾波器不是通過建立一個諧波通路濾波，因此，有源濾波器能夠將諧波的畸變功率這部分完整地節約下來，由此保證用戶端得到直接的節能收益。 Energy saving: Compared to passive filter, IFTSINE is not a harmonic path. IFTSINE can save the harmonic distortion power, thus providing the users receive the direct energy saving benefits.
靜止無功發生器
無功補償的意義信元瑞靜止無功發生器
隨著區域電網互聯的發展和負荷用電密度的增加，最大限度的發揮輸電線路的設計容量和提高系統的運行穩定性的問題就日益突出。要解決該問題，首先要考慮系統的電壓分布的情況,電力系統中的電壓分布的情況和系統中的無功潮流分布的關係十分的密切。因此，為了要調整系統的電壓分布，必須要調整系統中的無功潮流的分布。 在電力系統中，任何的用電裝置以及輸配電設備都要占用一定的無功功率。這時無功電流的存在使得線路的總電流加大，所以相對的增大了輸配電線路的有功損耗，從而造成了電壓下降、電能浪費，進一步惡化了電力系統電能質量。無功補償技術即是為了解決上述問題而提出的一種有效手段。 With the developing of area grid and increasing of loads, the problems of max using line-design capacity and improving system stability are more critical. To solve the problem it should be considered every bus voltage condition in the system first of all, while the voltage states have a close relation with the reactive power flow in the power system. Therefore to adjust the voltage of a grid, the reactive power flow must be adjusted. In power systems, any load device or transmission/distribution equipment occupies certain reactive power, which causes the reactive current that increases the line current. It makes the more active power consumption of transmission line, and brings about voltage drop, energy waste and taking to the worse for power quality further. The reactive power compensation technology is an effective method to solve the problems above.

IFTANGLE產品優勢（一） IFTANGLE與靜止無功補償SVC相比，存在很多優勢，主要表現在： IFTANGLE has many advantages comparing to SVC,its main performances are: 回響更加迅速，可完全替代原來的低壓無功補償設備； More fast,the device can completely replace the original low-voltage reactive power compensation equipment. 電壓變抑制更強 More ability to suppresses to voltage flickering. “有源設備”，運行範圍更寬 “Actire power”,More wide operation range. 能夠在一定範圍內提供有功功率 Provide active power. 抑制特定次諧波的能力強 Restrain certain harmonic. 電磁噪聲顯著降低 Lower electromagnetism noise. 設備占地面積顯著減少 Less occupation area. 功率損耗低，節電效果顯著 Less power loss, more energy saving. 能夠解決三相不平衡問題（三相三線制產品） The device can solve the problem of unbalance in three-phase three-line. 在設備補償範圍內可將功率因數提高到近似於1.0；能夠“吞吐”無功功率，實時連續補償，不合產生過補或者補償不足問題； The device can improve power factor to 1.0 within compensation ability. The device can output or absorb reactive power to gain real-time continuous compensation, will not cause excessive or inadequate compensation.
IFTANGLE產品優勢（二）
為更有效的提高電能質量，IFTANGLE靜止同步無功補償裝置已成為補償無功功率、改善電能質量的有力工具。該技術的核心器件IPM模組，比GTO元件具有更快的開關頻率，並且關斷容量已達到一定規模，因此NEWANGLE裝置具有更快的回響特性。 對於穩態時的電壓質量問題有許多成熟的措施加以解決；但對於動態電能質量問題，依靠傳統的無功補償和常規的濾波裝置則不能有效地解決，因為諸如電壓跌落（sage）、浪涌（surge）、電壓脈衝（impulse）與瞬時供電中斷（outage）這類電能質量問題持續的時間很短、變化很快，並且有的電能質量問題還伴隨著部分甚至全部的有功損失等情形。 IFTANGLE靜止同步無功補償裝置在SVC裝置的基礎上，克服了SVC產品由於呈恆阻抗特性，使得在電壓低時，無法提供所需的無功支持，應付突發事件的能力較弱；而且占地面積大，過多的SVC易引發系統振盪等弊端，IFTANGLE的無功電流輸出可以很大電壓變化範圍內恆定，在電壓低時仍能提供較強的無功支撐，並且可從感性到容性全範圍內連續調節，使得其無功輸出相當於同容量SVC的1.4—2倍；因IFTANGLE的靈活調壓，還可以大大減少變壓器分接頭的切換次數，從而減少分接頭故障次數。另外，IFTANGLE還可以抑制電壓閃變，提高系統暫態穩定水平，結合我國的國情和已有的技術，發展靜止同步無功補償技術應是解決我國電壓穩定問題的有效手段，並且也是FACTS技術發展的主要方向。 To more effectively improve the power quality, IFTANGLE SVG has become a powerful tool for reactive power compensation to improve the power quality. The core components of the IPM module technology have faster switching frequency than the GTO components, and its turn-off capacity has reached a certain size, so IFTANGLE device has a faster response. For the steady state voltage quality problems, many mature measures to solve them, but the dynamic power quality problems,the traditional and conventional reactive power compensateon device can not effectively filter solution, because the voltage drop, such as sags,surge,voltage pulse and the instanteous power interruption (outage), and these kinds of power quality problems persist for a short time, changing rapidly, and some power quality problems still associated with some or all of the active power losses circumstances. Based on the SVC, IFTANGLE has overcome the permanent impedance characteristic which causes that SVC is unable support var output,which provides weak ability to deal with thunderbolt in low voltage. Moreover the SVC area is big, excessively many SVC easy to initiate system vibration, the IFTANGLE’s var current may output in a very great voltage range of variation constant and could provide the strong work support in low voltage, and is with a scope adjust continuously. So its var output equals to co-content SVC 1.4—2 times. Because of IFTANGLE can adjust voltage, it may also reduce the operation number of transformer tapping greatly, which reduces tapping breakdown number, Moreover, IFTANGLE can suppress the voltage flickering, raise the system transition condition stable level, unified our country’s condition and the existing technology, which is national technology direction.
