Empowering smart highway development with intelligent power conversion systems

From July 27 to 28, 2022, the 24th China Expressway Informatization Conference and Technical Product Exhibition was held at the Changsha International Convention and Exhibition Center. Midas Electric participated in the event with its intelligent medium- and low-voltage automatic transfer switch product series, showcasing smart power supply solutions for expressway applications.

Since the construction of China’s first expressway—the Shanghai–Jiading 3200 Expressway—in the 1980s, the country’s expressway network has grown at an exceptional pace. According to data from the Ministry of Transport, by the end of 2021, China had completed 117,000 kilometers of expressways, ranking first in the world in total mileage. However, when adjusted for population and land area, there remains a notable gap compared with developed countries. In this new era, the national strategy to build a strong transportation system continues to accelerate the advancement of intelligent transportation. The digitalization, interconnection, and intelligent transformation of China’s expressways are progressing steadily. Looking forward, digital technologies will become more deeply integrated into the highway sector, driving the ongoing evolution and upgrading of smart expressways.

In recent years, the continuous expansion of expressway mileage has placed increasing pressure on highway management. Long-term, stable power supply and seamless switching of emergency power sources have become critical to ensuring the safe and orderly operation of expressways. Midas Electric focuses on power quality assurance and uninterrupted power supply in the transportation sector. Our independently developed medium- and low-voltage product series offer intelligent solutions to power supply challenges in expressway applications.

As a high-tech enterprise in the field of intelligent electrical systems, Midas Electric is committed to delivering intelligent power conversion systems and power quality products that help customers improve operational efficiency and service quality. In numerous expressway projects, our medium-voltage MDS9MV series switches, low-voltage MDS3/7/9 series switches, STS series switches, and other power quality products have played a key role in enabling seamless dual power source switching, minimizing power outage duration, and ensuring system stability.

The product series showcased at this exhibition include:

The MDS9MV series integrated medium-voltage ATS, featuring dual mechanical and electrical interlock designs along with intelligent control functions. It supports step-by-step load transfer to ensure smooth switching between dual power sources, effectively reducing power outage time on expressways.

The ME-iPOWER Intelligent Load Management System is an open, networked, modular, and configurable platform that integrates monitoring, control, communication, and maintenance. By combining real-time monitoring of operational conditions with multi-module data analysis, the system enables real-time supervision of expressway power supply performance, ensuring stable and continuous energy delivery.

The MDS9B series low-voltage bypass ATS is suitable for high-capacity power distribution systems and critical load applications. It supports live maintenance, meeting the strict power reliability requirements of expressways.

The PowerSwift series STS rapidly evaluates the status of power sources and selects the optimal one, meeting the fast-switching demands of expressway power supply systems.

In addition, the MDVR series dynamic voltage regulation devices were also on display. These units utilize DSP, FPGA, and CPLD control chips to monitor voltage quality in real time. When a voltage sag or surge is detected, the system seamlessly switches the downstream load to inverter power, ensuring uninterrupted power for sensitive equipment.

During the 14th Five-Year Plan period, China is entering a crucial stage in its efforts to accelerate the development of a strong transportation nation. The informatization, digitalization, and intelligent transformation of expressways are key indicators of the modernization of the transport sector. Looking ahead, Midas Electric will continue to leverage its strengths in intelligent power conversion, working hand in hand with industry partners to drive digital transformation, promote the deep integration of digital technologies with expressways, and contribute to the advancement of smart expressway construction.
