China and IEC international standardization activities

International Electrotechnical Commission (IEC), one of the currently worlswide largest and most authoritative international standardization organizations,is specialized in developing and promulgating international standards for the electric and electronic fields, which are widespread adopted through out the world and play an important role in the international trade of electric and electronic products. Moreover, according to the 2005 statistics by the World Bank, the population of countries participating in the IEC activities accounts for 92% of the world total and their trade volume accounts for 95% of the global total. ……

First IEC standard of DC bias suppression devices to be issued

IEC TS 60076-23,the first IEC standard on DC bias suppression devices approved by IEC/TC 14 in November 2017,is expected to be published and put into force in 2018,overcoming the lack of such IEC standards in the field.The Shanghai branch of SGCC has carried out studies and researches on DC bias effect for more than 10 years,and it has led the standard development based on its R&D and the application of DC bias suppression devices in China.

Review and Outlook of China Electronic and IT Industry Footprints in IEC International Standardization Activities

Year 2006 is the year marking the 100th anniversary of the founding of International Electrotechnical Commission (IEC). IEC is mainly engaged in the international standardization for electrical and electronic technology field aiming at promoting international trade and technology cooperation and exchange, improving product and service quality, upgrading productivity and protecting the environment as well as human health and safety. Most countries worldwide adopt standards developed and promulgated by IEC, providing a platform to international trade and technical exchange. China has being a member since 1957. Electronic and IT are the most developed and energetic filed in recent decades. Number of IEC TC/SC specialized in electronic and IT amounts up to 52.……

As an integral part of electrical and electronic product portfolio, Household electrical product development has also been directly influenced by IEC.……

An Improved Security Scheme for IEC 61850MMS Messages in Intelligent Substation Communication Networks

Advanced connectivity in substations brings along cybersecurity considerations. Especially, the use of standardized data objects and message structures stipulated by IEC 61850 makes them much more vulnerable to unauthorized access and manipulation. In order to tackle these vulnerabilities, different methods are investigated by researchers all over the world. An important aspect of such efforts is the real-time performance consideration since power systems are bound by the rules of physics and all control/communication tasks need to be completed in a certain time frame. Security schemes for substation communication have been proposed in the recent literature. However, they must be improved to ensure a full security solution. Recently published IEC 62351 standard aims to fill this gap. Node authentication is vital for substation communication networks based on IEC 61850 to mitigate a variety of attacks such as man-in-the-middle(MITM) attack. This short communication presents a node authentication mechanism based on transport layer security(TLS) with certificates to address this knowledge gap. It also investigates the real-time performance by implementing the proposed scheme with Python.
