讲座题目：High Fault Current Synchronous Condensers for Support of Renewable Grids
讲座内容：With an increasing share of renewable energy sources being connected to electrical power networks, transient energy from the rotating inertia of traditional power plant is reducing. Renewable energy resources are highly dynamic and somewhat intermittent compared to more traditional generation sources. Hence, they pose a challenge to the electrical network operator in terms of effectively managing their resources to maximize energy transfer while maintaining stable operation. Existing renewable generation normally has low transient energy, which reduces system inertia. This increases the specification requirements of other interconnected components. Specifically, the physical characteristics of power electronics limits the output current of renewable schemes during fault. The presentation will initially discuss the operational concept of a synchronous condenser with reference to the support of renewable and localized embedded generation. An example synchronous condenser design is presented to illustrate the provision of some limited energy input during energy transients, some reactive VAR capability, but importantly, supply of high transient fault currents. The presentation discusses the synchronous condenser electro-magnetic design to realize high fault levels.
专家简介:
Nigel Schofield received the degrees of B.Eng. (Hons.) in Electrical Power Engineering, and Ph.D. for research on the field-weakening capability of brushless permanent-magnet traction machines, from the University of Sheffield, UK, in 1990 and 1997, respectively. During the period 1993 to 1995 he served as a Senior Experimental Officer in the Department of Electronic and Electrical Engineering (EEE) at the University of Sheffield, before taking up the post of Design Engineer in industry.
From 1997 to 2001, Dr. Schofield was a post-doctoral researcher in the Electrical Machines and Drives Research Group, Dept. of EEE, University of Sheffield, and from 2001 to 2004 a Lecturer in the Dept. of EEE. On 1 July 2004 he was appointed to a Mechatronics Lectureship in the School of Electrical and Electronic Engineering, at the University of Manchester, UK, and a Senior Lecturer in the School in 2009 where he lectured across all undergraduate years and on the Power Conversion M.Sc. On 1 Jan. 2013 Dr. Schofield joined the Department of Electrical and Computer Engineering at McMaster University, Ontario, Canada, as a Full Professor with Tenure. On 1 May 2017 Dr. Schofield joined University of Huddersfield, UK. His research interests include electro-magnetic power-trains for all- and hybrid-electric vehicles; the vehicular application of electro-chemical and electro-static energy sources; hydrogen fuel cell systems; aerospace machines and actuators; the industrial application of electro-magnetic devices and wind generator design and renewable energy schemes. Prof. Schofield is a Chartered Engineer and member of the UK IET and IEEE.
