In 2009, the United States proposed new energy to resist the financial crisis and revitalize the economystrategyAnd start the construction of smart grid. Under this promotion, the construction of smart grids has also begun.

The smart grid in the United States is the construction of a unified power grid spanning four time zones, which can gradually achieve the unified integration of solar energy, wind energy, geothermal energy, etc., comprehensively promote distributed energy management, and thus improve the reliability and energy utilization efficiency of the power grid operation. Recently, the United States announced the implementation of smart grid construction, laying or updating 3000 miles of transmission lines and installing smart meters for 40 million households.

In China, the National Energy Work Conference held in February this year proposed to increase investment in power grid construction and renovation, and achieve coordinated development between the power grid and power sources. State Grid Corporation of China proposes to accelerate the construction of a unified and strong smart grid with ultra-high voltage power grid as the backbone, coordinated development of power grids at all levels, and characteristics of informatization, digitization, automation, and interactivity. The construction of smart grid in our country has also begun.

Analysts say that smart grid planning will effectively stimulate sub industries such as smart meters, digital substations, system integration and metering systems in the short term, not only forinstrumentation and metersProvide a large market space and also promote electrical engineeringinstrumentation and metersThe development of industry technology.

The core of a smart grid lies in building an intelligent network system that integrates multiple energy sources with intelligent judgment and adaptive regulation capabilities and distributed management. It can monitor and collect real-time electricity consumption information of the grid and users, and use the safest transmission and distribution methods to deliver electricity to end users, achieving the configuration and utilization of electricity and improving the reliability and energy utilization efficiency of grid operation.

The essence of smart grid is energy substitution and compatible utilization, which requires integrating data in the system and optimizing the operation of the grid based on open systems and shared information modelsmanagementThe open integrated network system will change today's power grid structure, achieving full process control from energy access, transmission and distribution scheduling, safety monitoring and relay protection, user electricity information collection, metering and billing, to delivering electrical energy to users.

The core and essence of smart grid require electricians to include energy meters, power transmitters, indicating instruments, and various sampling devicesinstrumentation and metersDeveloping towards multi parameter intelligent information sampling terminals. Intelligent terminals will also have functions such as centralized information sampling, unified calling, and distributed processing. At the same time, they can be transmitted, stored, and displayed on demand, and have plug and play functionality.

Benefiting from the power user electricity information collection system and the construction of smart grids, there will be significant demand in both domestic and domestic markets. Experts point out that in the coming period, technological innovation and the ability to develop smart meters will become the determining factorselectricianinstrumentation and metersThe key factors for the success or failure of a business. At the same time, the increase in energy conservation and emission reduction efforts will further accelerate the update speed of products, and related power quality analysis equipment, power grid safety monitoring equipment, automatic testing systems, and virtual instruments will also become new hotspots.
