What Does a 3rd Class Power Engineer Do?

Power engineers are engaged in surveying, planning, designing, power engineering construction, installation, commissioning, technology development, test research, power generation operation, maintenance, repair, power grid dispatching, power management, power environmental protection, power automation, and technical management. Power engineering and technical personnel. The electric power industry is an important industry of the national economy. It was a bottleneck industry in the development of the national economy. However, due to the structural contradictions, it still cannot fully adapt to the development of the national economy, and there is still great development potential.

China's power grid voltage is divided into: 1000kV, 800kV, 500kV, 330kV, 220kV, 110kV, 66kV, 35kV, 20kV, 10kV, 380V, 220V, among which 1000kV-110 (66) kV is the transmission grid, 35kV-10kV is the distribution network. Due to the "re-transmitting light but not supplying" in the past years, the proportion of grid investment is much lower than that of developed countries, especially the distribution network is relatively backward.

1.Research and development

The investment in modern power must accompany the demand for power automation equipment. Investment in electric power automation, mainly in urban network transformation, will greatly reduce the average outage time, improve power supply reliability, and have huge economic benefits for the entire society. However, from the perspective of power companies, because China has not yet established a comprehensive power outage compensation system, the economic benefits brought by power automation investment to power companies are not large enough, which has affected the enthusiasm of power companies for investment in power automation to some extent. . The high complexity of power distribution makes power supply companies have to control the entire distribution network. The power distribution systems of modern big cities in developed countries are based on a rational network planning, reliable power transformation equipment itself with remote control and intelligent functions, the popularity of information systems, and the diversification of consumer demand. automation.

Japan began to solve the problem of power distribution in large cities in the 1970s. From the 1980s to the present, it has completed distribution automation systems that coordinate computer systems with power distribution equipment in major cities. The United States achieved a certain degree of distribution automation in the 1980s. South Korea, Taiwan, China also completed the automation of local power distribution systems in the 1990s. At present, the main contradiction in China's power grid lies in the distribution network. China's distribution network is weak, with poor reliability, high losses, poor voltage quality, and low degree of automation. Most cities are basically radiant single-ended power supplies. Once the line fails, the entire line can only be cut off, resulting in a large-scale power outage. The State Power Corporation plans to automate the 10KV distribution network in China's cities by 2011 and increase the reliability of urban power supply to 99.99%. The final power distribution network will be a hand-in-hand ring structure, powered by dual power sources. When a line fails, it will be isolated between the two switches by a series of switching operations of the power distribution automation system, while other non- Restore power to the faulty area.

China still lacks the material basis for large-scale realization of distribution automation in low- and medium-voltage distribution networks, but distribution automation is certainly the future development direction, and improving the quality of data collection and communication systems is a prerequisite. The technology of power distribution automation is more difficult than dispatch automation. It directly serves tens of millions of power users, and its market capacity is much larger than dispatch automation. Therefore, in the long run, the power automation market will grow steadily.
