On December 12, at the 500 kV Jiangling converter station ± by Hubei DC Company abroad, Yang Peng, the person in charge of the work, completed the last Ancuo, and the country's first ultra-high pressure converter station converter protection load simulation polarity calibration work officially began. On the same day, the on-site staff carried out the calibration and debugging of the test instrument to ensure that the equipment was in good condition.
According to reports, the simulation test is a major innovation carried out by the State Grid Hubei DC Company, the test device used to use capacitance compensation boost technology, so that the output of high voltage and high current can be achieved under low power, compared with the traditional high-power primary current voltage device volume is greatly reduced. Through this work, the problem of simulated polarity verification of commutation variable protection load was successfully solved, and the safe and stable operation of the large power grid was escorted.
Background: The stable operation of large power grids is crucial to the normal operation of the national power system. However, the polarity verification of the protective load simulation of the ultra-high pressure converter station has always been a difficult problem, and the traditional polarity verification mode with load has problems such as large workload and long time, in order to solve this problem, the State Grid Hubei DC Company has carried out exploration and innovation, and successfully carried out this historic test through the application of new technology and devices.
Insight: The application of this new technology not only solves the problems existing in the traditional test mode, but also provides more guarantees for the operational stability of the power system. Behind this initiative, it reflects the importance and strength of the State Grid Corporation of China for technological innovation.
The reason behind the problem: the traditional load polarity check mode has problems such as large workload, long time, and also brings potential safety hazards. Therefore, it is necessary to explore new technologies and new models to improve detection efficiency and accuracy, and have a positive impact on the operational stability of the power system.
Legal and Policy Analysis: The State Grid Corporation of China has been committed to technological innovation and safe production, and this successful trial also reflects the guidance and support of relevant laws and policies. In the future, it is expected to continue to promote the application of new technologies in the power system, and propose more specific laws, regulations and standards.
International perspectives and suggestions: Some advanced technologies and experiences from abroad can provide us with reference, and at the same time, technical exchanges and cooperation can be carried out to promote the safe operation and technological development of the power system.
Summary and suggestions: The success of this test is the embodiment of the technical strength and innovation ability of State Grid Hubei DC Company, and also provides more guarantee for the operation stability of the power system. In the future, it is hoped that the company will continue to promote the application of advanced technology in the power system and improve the stability and safety of the power system.
