Analyze the development trend of future low-voltage intelligent power distribution system

Indicate full selectivity protection as the future direction of low-voltage smart distribution systems

On September 13, 2013, the 5th Low-voltage Intelligent Distribution System Technology Forum (Jinan Station) was successfully held. The forum was sponsored by the "Low-Voltage Electrical Apparatus" magazine of the Shanghai Electric Apparatus Research Institute, the Architectural and Electrical Professional Committee of the Civil Engineering and Architecture Society of Shandong Province, the Shandong Electric Power Technology Information Network, the Shandong Electric Power Enterprise Association, the Shandong Electric Engineering Society, and the Shandong Institute of Automation. With strong support and assistance from local academic organizations, well-known companies at home and abroad in the low-voltage electrical appliance industry: Siemens (China) Co., Ltd., Delixi Electric Co., Ltd., Hangshen Group Co., Ltd., and Beijing Mingri Electric Appliance Co., Ltd. co-organized.

The guests present at the forum included General Secretary of the General Electric Low-voltage Appliances Branch of the China Electrical Equipment Industry Association and Professor Yin Tianwen, Dean of the Shanghai Research Institute of Electrical Engineering; Deputy Chief Engineer of East China Architectural Design and Research Institute Co., Ltd., Executive Director of the National Construction Electrical Design Information Network, and China Construction. Mr. Shao Minjie, Chairman of Shanghai Electrical Engineering Design Research Association; Executive Vice Chairman of Architectural Electrical Engineering Committee of Shandong Civil Engineering Society; Chief Engineer of Institute of Architectural Design Institute of Shandong Province; Zhang Jian; Shandong Construction Electrical Technology Information Network Honorary Chairman Wu Enyuan. Nearly 180 experts and representatives from design institutes, power systems, complete sets of electrical appliances, real estate, chemical engineering and application fields attended the meeting.

The forum was first addressed by Zhang Yuqing, Editor-in-Chief of Low Voltage Electrical Appliances. In his speech, he said that “Low-Voltage Electrical Apparatus”, as the responsible media of the low-voltage distribution industry, has the responsibility and obligation to build a platform for mutual communication between production, learning and research, and to make due contributions to the promotion of technological progress in the industry. In the context of the smart grid construction, the forum focused on low-voltage intelligent power distribution systems. Through the introduction of the latest technologies and solutions by senior industry experts and well-known enterprises, the local power distribution industry in Anhui Province was promoted.

Zhang Hao, speaking on behalf of the Shandong Provincial Society, delivered a speech. Zhang Zong spoke highly of the holding of this technical exchange forum. The topics focused on the low-voltage intelligent power distribution system, and talked about the most selective protection, circuit breaker selection, and intelligence in Shandong Province. Topics such as power distribution systems and building energy conservation monitoring, setting up a platform for in-depth technical exchanges and promoting technological progress in the distribution industry in Shandong Province, Zhang expressed his welcome and expectation, and wished the conference a complete success.

The forum invited well-known domestic experts to talk about the development trend of smart electrical technology, the correct selection of circuit breakers in low-voltage power distribution systems, new technologies for low-voltage circuit breakers, and building energy conservation monitoring. Dean Yin Tianwen brought a report on the development trend of smart electrical appliances and system technology. In the report, he introduced the technical development trends of smart appliances and the technical development trends and key technologies of the smart grid user-end systems. Shao Minjie’s general work is the national architectural electrical design master. In the report, he shared his experience and understanding of the correct selection of circuit breakers in low-voltage power distribution systems and the common problems of selective protection. In particular, he shared the electrical designers’ design process in peacetime. Frequently encountered confusion and distressed responses have benefited the electrical designers present. Wu Enyuan brought a report on the "Design Outline for the Construction Drawings of the Energy-saving Monitoring System for Public Buildings", which is a good guide for local electrical engineers to do a good job in building energy-saving monitoring and design.

In order to better serve the purpose of deep communication between industry, universities and research institutes, this forum invites well-known companies in the industry: Siemens, Delixi Electric, Hangshen, and Beijing tomorrow to explain their latest technologies and solutions. Delixi Electric brought intelligent low-voltage power distribution control solutions and introduced its latest technologies and products, including Delixi Electric's new era product family: CDW9 universal circuit breakers, CDM9 molded case circuit breakers, and CDB9 series low-voltage terminals. Electrical products will enable delegates to learn more about the latest products and technologies from the Delixi Electric family. Siemens brought the "Siemens low-voltage power distribution system design selection software" report. Hangshen Group introduced its "Intelligent Network and Distribution System" solution in detail.

The forum experts and reports from various companies carried out in-depth discussions and research on the concerns of electric designers in the “Intelligent Power Distribution System” and seized the industry’s hot spots in content. The atmosphere at the meeting was warm and the participants were very strong. The attractiveness of the experts was carefully prepared and the speeches of the entire conference were wonderful and rich. They provided a platform for the participants to learn and exchange and contributed to the sustained and healthy development of the low-voltage electrical appliance industry.
