July 24，The 28th "Jingweiyun" Postgraduate Academic Thought Forum of the School of Electrical Engineering was successfully held。The forum invites He Junfeng, a power system analysis and R&D expert from NARI Relay Protection Research Institute、Department Manager Xu Guangfu spoke about “promoting the research and practice of key technologies in the construction of new power systems”、Sharing on the theme of "Active Distribution Network Control and Protection Technology"。Secretary of the Party Committee of the Research Institute of NARI Relay Electrical Co., Ltd.、Vice Dean Li Haiying、Zhang Chunhe, deputy chief engineer of the institute、Yin Lumin, Secretary of the Party Committee of the School of Electrical Engineering、Assistant to the Dean、Professor Sun Yuanyuan and college teachers、Student representatives attended the event。The forum is hosted by Ye Hua, Vice Dean of the School of Electrical Engineering。
He Junfeng looks at the main risks and challenges faced by the current power grid、Explain the ideas and technical framework to deal with challenges and the practice of NR in promoting the construction of new power systems。At the same time，He Junfeng's grid-based energy storage technology and research progress、Typical flexible control technology for large power grids、Key technologies for wide-band oscillation prevention and control and new energy rapid power control technology are highlighted in four parts，Explained the network configuration STATCOM、Construction status of grid-connected energy storage power stations and current application status of flexible DC transmission technology，The explanation method is from simple to profound，Easy to understand。
Xu Guangfu first introduced his work experience since joining Nari Relay Protection Company，During work，Took the lead in developing the first set of distributed power generation grid-connected interface devices in China、Microgrid control and protection complete equipment and active distribution network control and protection complete equipment，All identified as internationally leading。He pointed out，my country’s efforts to achieve “carbon peak”、Carbon Neutral "Goal，Proposed the goal of building a new power system with new energy as the main body，But there are many challenges and key technologies that need breakthrough，Including active distribution network protection technology、On-site flexible control technology and main distribution collaborative emergency control technology。final，He pointed out the selectivity of extremely high penetration distributed photovoltaic access to existing distribution network protection、Sensitivity may have a non-negligible impact，It is necessary to study new protection solutions，Improve the applicability of protection。
Communication and question session，He Junfeng and Xu Guangfu proposed the development trend of power electronic equipment cost for teachers and students、Current engineering practice application status of energy storage equipment、Patiently answer questions such as the distribution of measurement equipment in my country's distribution network。
Li Haiying makes a concluding speech。He said that he attaches great importance to school-enterprise cooperation，Care about the scientific research study and life of students during their postgraduate period，To all the leaders of the School of Electrical Engineering of Shandong University、Thank you for the hard work of the teacher。I hope students will broaden their horizons，Improve the level of scientific research，Combining personal ideals with national needs，Dedicate yourself wholeheartedly to scientific research，Contribute to the development of the national electric power industry。
final，The 28th "Jingweiyun" Postgraduate Academic Thought Forum ended successfully with applause，Leaders attending the meeting、Teachers take a group photo。
