Online monitoring solution for high-speed train traction system

The 14th Five Year Plan for Railway Science and Technology Innovation clearly states that railways are the backbone of the comprehensive transportation system, an important support for building a modern economic system, and a leading field for the comprehensive construction of a socialist modernized country. Railway technological innovation is an important component of the national scientific and technological innovation system and the primary driving force behind the development of railways. Focus on key technologies in the field of equipment, promote the development of high-speed intelligent high-speed trains, advanced transportation equipment, and modern engineering equipment, accelerate the research and development of key core technologies, promote the high-end, intelligent, and systematic development of technical equipment, and create a modern equipment system.

In addition, many important national policies such as the "Medium - and Long Term Railway Network Plan", "Thirteenth Five Year Plan for National Science and Technology Innovation", "Made in China 2025", and "Guiding Catalogue for Industrial Structure Adjustment" have made clear plans for railway infrastructure, transportation equipment and core technologies, key components, and other fields, encouraging and supporting the development and progress of these areas. This will play a positive role in promoting the sustained and rapid development of the rail transit vehicle parts manufacturing industry and enterprises.

China's high-speed railway and the "the Belt and Road" are both the "golden cards" of China's development in the new era. They complement each other like "two wings of a bird", providing a strong guarantee for China's going global and connectivity with countries around the world. China has independent intellectual property rights of many technologies in high-speed railway construction, while the "the Belt and Road" reflects the essence of China's "harmony" culture. At this moment, profound cultural connotation and advanced modern technology blend together, allowing the realization of the Chinese dream to enter a fast lane.

The year 2023 will be the tenth anniversary of the proposal of jointly building the "the Belt and Road". In the past decade, the joint construction of the "the Belt and Road" has achieved remarkable results, and witnessed the rapid development of China's high-speed railway in the world. As a landmark infrastructure construction project, China's high-speed rail is leading the progress of the global high-speed rail industry with its excellent technology and reliable quality. From technology, infrastructure to economic drive, China's high-speed railway plays an important role in the "the Belt and Road" initiative.

The high-speed train transportation industry has increasingly high requirements for the reliability and efficiency of traction systems. As the core of the traction system, the performance of the power converter is directly related to the operational efficiency, energy consumption, and overall system reliability of the train.

The industry needs an efficient online monitoring solution to detect potential issues with power converters in advance, reducing train downtime and maintenance costs. For high-speed trains, it is crucial to respond quickly and accurately and solve traction system problems to ensure train safety and improve operational efficiency.

The demand for preventive maintenance of power converters is increasing among operators and maintenance teams to improve system availability and extend the lifespan of power converters.

The power converter is a key component of the high-speed train traction system, responsible for converting DC power into AC power to drive the operation of the train. By monitoring the key parameters of the power converter in real-time, the stability, efficiency, and safety of high-speed trains during high-speed operation can be ensured. During train operation, by comprehensively monitoring the operating status of the power converter, real-time performance data is provided to the operator to support precise control and maintenance of the traction system.
