It is the second batch of national innovative pilot enterprises, "National Torch Program Key High-tech Enterprises", "China Top 100 Software Enterprises" and "China Top 10 Self-owned Brand Software Enterprises". Huarui Group Company is mainly engaged in R&D, production and sales of high-voltage test instruments, measuring and test instruments, high-voltage cable accessories and lightning protection and grounding products. In 2008, according to the requirements of the 17th National Congress of the Communist Party of China and the State-owned Assets Supervision and Administration Commission on deepening the reform of state-owned enterprises and improving the modern enterprise system, the State Grid Electric Power Research Institute summarized.
Combined with the development planning of State Grid Corporation and the development reality of State Grid Electric Power Research Institute, a new round of enterprise strategic management planning is actively carried out. Short-term strategic goal: to develop technologies and equipment with independent intellectual property rights in major scientific research and industrial development fields, and to become a leader in the development of power system automation, AC /DC high-voltage technology, water conservancy and hydropower engineering measurement and control, communication and information engineering, intelligent primary equipment and power electronics technology in China and a major provider of important technical equipment. Medium-and long-term strategic goal: Through industrial expansion and international development, realize the "three-thirds system" market structure, become an internationally renowned high-tech enterprise, and enhance the international influence of State Grid Corporation in related technical fields. Development goal: Carry forward the enterprise spirit of "striving to surpass and pursue Excellence", firmly establish the management concept of "collectivization, intensification, lean and standardization" around the "first-class and four modernizations" scientific and technological development strategy and the development needs of State Grid Corporation and industry, strive to improve the independent innovation ability, support service ability and market competitiveness, and implement its own development strategic plan in providing strong technical support and services for State Grid Corporation to realize "two transformations".
