2020Year1month9Sunday morning，By Graduate School of Shandong University、Sponsored by the Postgraduate Affairs Department of the Party Committee，Hosted by the School of Electrical Engineering5Issue(General No.927Issue)"Ji Xia Feng"The graduate academic forum is held in the lecture hall on the fourth floor of the Electric Power Building on Qianfoshan Campus。Associate Professor Lin Zhenzhi from the School of Electrical Engineering, Zhejiang University was invited to this forum，The topic of the lecture is“Mining and application of big data in power low-voltage measurement”. This forum was hosted by Professor Wang Hongtao.

Report begins，Lin Zhenzhi introduced the background of the ubiquitous power Internet of Things，Proposed the ubiquitous power Internet of Things，The concept of providing comprehensive energy services to low-voltage users，This leads to the topic of mining and application of power low-voltage measurement big data。He first introduced the comprehensive evaluation of the operation quality of metering equipment based on measurement big data，Detailed explanation of various indicators and data processing methods for quality evaluation of operating equipment；Continue，Introducing several common methods for abnormal power consumption detection of special transformers based on measurement big data；Then，Lin Zhenzhi introduced the relationship between Taiwan and households、This part of phase identification and fault identification methods，And show students their research results through actual cases。final，He analyzed the shortcomings of existing methods，And shows future research directions。Question session，Lin Zhenzhi separately asked whether the clustering method is based on three-phase voltage data、The teacher and students were given corresponding answers on the specific concepts of principal component analysis and the method used in combining weights during anomaly detection。In addition，Associate Professor Lin enthusiastically told the students about his scientific research process，And shared his experience and skills when publishing papers。

This issue of the "Jixiafeng" postgraduate academic forum came to a successful conclusion with warm applause from teachers and students。After the meeting，The guest speaker took a group photo with all the staff。
