Intelligent distribution network equipment is still looking forward to national standards

The second working group meeting of the “smart grid standardization roadmap” project under the “Study on Key Technical Standards for Intelligent Power Transmission and Distribution Equipment” was recently held in Beijing. This topic is the first large-scale intelligent equipment standard research in equipment manufacturing.

Jin Qiang, Deputy Chief Engineer of Xi'an Xideng High-Pressure Casing Co., Ltd., a member of the Task Force, focused on issues concerning the production, operation, maintenance, and testing of insulators, and explained the evaluation methods for insulator systems and insulating materials for UHV outdoor insulators. Drafting of standards. The meeting organized the work on the follow-up work of the "Study on Key Technical Standards for Intelligent Transmission and Distribution Equipment" and the preparation of the "Evaluation Method for Insulators and Insulating Materials for UHV Outdoor Uses" standard.

With the gradual deepening of smart grids, distribution network equipment has gradually developed toward intelligentization, digitization, and automation. As a result, relevant intelligent network distribution equipment lacks related technical standards, and many existing standards require further modifications. And perfection, whether it is for the entire distribution network, or for the majority of distribution network equipment companies, the introduction of national standards as soon as possible will undoubtedly become an important task.

In fact, the State Grid Corporation of China has previously issued two management standards for “Standards for Management of Distribution Network Condition Maintenance and Work Standards (Trial)” and “Test Procedures for State Maintenance of Distribution Network Equipment” and “Guidelines for Stateful Maintenance of Distribution Network Equipment”. "Equipment status evaluation guidelines" three technical standards. At this point, a standard system for state maintenance of distribution networks has been formed, which provides institutional guarantees and technical basis for the full implementation of distribution network status overhaul of distribution network systems.

In July 2012, Beijing Electrotechnical and Economic Research Institute of Machinery Industry held a meeting to discuss the key technical standard project of intelligent transmission and distribution equipment in Beijing. This is considered as the start of the National Energy Application Technology Research and Engineering Demonstration Project “Intelligent Power Transmission and Distribution Key Equipment Development and Engineering Application Demonstration” Topic 8 and “Study on the Key Technical Standard Project of Intelligent Power Transmission and Distribution Equipment”.

The meeting made it clear that, in order to establish a standard system for intelligent transmission and distribution equipment in China, standard research was conducted at the same time as equipment development and testing base construction, and intelligent transformers, intelligent reactors, intelligent tank circuit breakers, and intelligent GIS were completed. The development of technical specifications and standards for key equipment such as distribution, to meet the requirements of the development of smart grid technology in China.

Although the continuous upgrading of smart grid and distribution automation has raised new and higher requirements for related equipment, the domestic development ideas and direction of smart grids, especially equipment upgrading and upgrading in intelligent substations, have provided effective research for the subject. Support and application practices.

"Standard formulation should be combined with the requirements of relevant grid companies, closely integrated with project demonstration projects, and be compatible with China's smart grid standard system." Yang Qiming, executive vice president of China Electrical Equipment Industry Association, stated that the national "Twelfth Five-Year Plan" is clear The goal of smart grid construction was proposed. The China Electrical Appliance Industry Association also carried out standardization work in the field of smart grid equipment, established a smart grid equipment working committee and assumed the national smart grid standardization work promotion group and the smart grid equipment standardization group leader unit. Smart grid equipment technology development route and smart grid equipment standard system framework.

In addition, some experts suggested that the establishment of intelligent transmission and distribution standards should be the support for the demonstration project construction, strictly in accordance with the provisions of scientific research management, according to the requirements of the overall project team to arrange the progress of work, closely integrated with the work of the State Grid Corporation of China Southern Power Grid Corporation Directions and working ideas to meet the requirements of power users. The standard revision and the development of intelligent transmission and distribution equipment were carried out simultaneously.

Hu Shuqing, director of the China Machinery Industry Federation, believes that the research content of the project should be combined with the other seven subprojects of the project, and the standards developed should be linked with other sub-projects. It needs to integrate with existing demonstration projects and existing standard systems, and do a good job of budgeting and project management. We will increase the research work on power capacitors and gradually carry out upgrades and transformations of intelligent transmission and distribution equipment in different links such as transmission and distribution.
