5SHY4045L0001 高壓大容量功率半導體器件作為MMC
5SHY4045L0001 在新能源輸送和大規(guī)模儲能的驅動下，直流電網在世界各國的發(fā)展勢不可擋。高壓大容量功率半導體器件作為MMC、直流斷路器、直流變壓器、直流耗能裝置等直流主干網絡關鍵裝備的核心元件，是學術研究的前沿話題，也是產業(yè)應用的關注熱點。IGBT具有驅動功率小而且驅動電路簡單、開關速度快、耐壓高、電流大等優(yōu)點，在柔性直流電網中得到了廣泛的應用。而事實上，盡管IGBT優(yōu)勢突出，但是相比電流型器件，仍然存在通態(tài)壓降大、可靠性低、制造成本高等問題，具有很多改進的空間。尤其是在高壓大容量應用中，所使用的開關器件數量非常大，若能改進這些特性，進一步提高效率和可靠性、減小成本，將會具有很大的吸引力和應用前景。5SHY4045L0001在突破IGCT器件新技術的同時，研究團隊對于IGCT器件在直流電網中的應用前景進行了系統地分析和展望，同步研制了一系列關鍵設備，并在示范工程及電網試驗平臺中得到了應用。當前直流電網中的關鍵設備（如MMC、直流斷路器、直流變壓器、直流耗能裝置等）相對于交流電網中的電力電子設備具有很多新特性，這為IGCT的應用提供了契機。研究團隊結合這些關鍵設備的內在特性，提出了基于IGCT的創(chuàng)新方案，并系統論證了其可行性以及技術經濟優(yōu)勢。分析表明，基于IGCT的新型設備在安全防爆、故障處理、轉換效率、功率密度、制造成本以及可靠性等方面均具有突出的優(yōu)勢，使其在直流電網中的應用具備巨大的潛力。在2018年12月投運的珠海“互聯網+”智慧能源示范工程中，雞山換流站的10kV/10MW MMC應用了研究團隊提出的IGCT交叉鉗位方案，這是國產IGCT器件在柔性直流輸電換流閥中的首次亮相?，F已穩(wěn)定運行一年多，為IGCT器件特性的研究和改進提供了寶貴的數據和經驗。在正在建設中的東莞交直流混合配電網工程中，應用了基于IGCT-Plus研發(fā)的±375V固態(tài)式直流斷路器，實現了國產IGCT-Plus器件在固態(tài)式直流斷路器中的首次應用。

Driven by new energy transmission and large-scale energy storage, the development of DC power grids in countries around the world is unstoppable. As the core components of key equipment of DC backbone network such as MMC, DC circuit breaker, DC transformer and DC energy consuming device, high-voltage and large-capacity power semiconductor device is the frontier topic of academic research and the focus of industrial application. IGBT has the advantages of low driving power, simple driving circuit, fast switching speed, high voltage and high current, and has been widely used in the flexible DC power grid. In fact, despite the outstanding advantages of IGBT, compared with current-type devices, there are still problems such as large on-state voltage drop, low reliability and high manufacturing cost, and there is a lot of room for improvement. Especially in high-voltage large-capacity applications, the number of switching devices used is very large, and if these characteristics can be improved to further improve efficiency and reliability, and reduce costs, it will have great attraction and application prospects. 5SHY4045L0001 While breaking through the new technology of IGCT devices, the research team systematically analyzed and forecast the application prospects of IGCT devices in DC power grids, synchronously developed a series of key equipment, and has been applied in demonstration projects and power grid test platforms. The key equipment in the current DC power grid (such as MMC, DC circuit breaker, DC transformer, DC energy-consuming device, etc.) has many new characteristics compared with the power electronic equipment in the AC power grid, which provides an opportunity for the application of IGCT. Combining the intrinsic characteristics of these key devices, the research team proposed an innovative scheme based on IGCT, and systematically demonstrated its feasibility and technical and economic advantages. The analysis shows that the new type of equipment based on IGCT has outstanding advantages in safety and explosion protection, fault handling, conversion efficiency, power density, manufacturing cost and reliability, which makes its application in DC power grid have great potential. In the Zhuhai “Internet +” smart energy demonstration project put into operation in December 2018, the 10kV/10MW MMC of Jishan Converter station applied the IGCT cross-clamping scheme proposed by the research team, which is the first appearance of domestic IGCT devices in the flexible DC transmission converter valve. It has been running stably for more than one year, providing valuable data and experience for the research and improvement of IGCT device characteristics. The ±375V solid-state DC circuit breaker developed based on IGCT-Plus is applied in the AC-DC hybrid power distribution network project under construction in Dongguan, which realizes the first application of domestic IGCT-Plus device in solid-state DC circuit breaker.
