Recently, two technological achievements independently developed by Willfar Information—the Remote Terminal Unit (RTU) and the WFET-2000 Station Energy Acquisition Terminal—passed the scientific and technological achievement evaluation organized by the Hunan Instrument and Meter Industry Association. An authoritative panel composed of power industry experts from Shandong, Chongqing, Yunnan, and professors from Hunan University and Changsha University of Science and Technology concluded:The RTU’s overall technical level reaches the internationally advanced level, with several core indicators breaking through industry bottlenecks.The WFET-2000 Station Energy Acquisition Terminal has achieved full-chain domestic substitution, attaining a domestically leading technical level.
This marks another Milestone innovation for Willfar Information in the field of power automation following its breakthrough in chip technology in 2024. It demonstrates China’s power equipment now possesses the capability to compete globally in technology within the domains of Distribution network measurement/control and energy acquisition.
The Integrated Measurement and Control Terminal (RTU) independently developed by Willfar Information is specially designed for the complex distribution network environment and strictly follows the IEC international standard. The product has industry innovation in many aspects, and its technical level was recognized as international advanced by the expert group on site. The terminal product project has invented a low - power high - sensitivity residual voltage fault detection technology based on interrupt wake - up, which realizes that the working current is less than 20uA and can detect the residual voltage fault signal with the shortest 5ms, significantly improving the accuracy of power grid fault selective protection; invented a grounding fault judgment method with multi - feature fusion, improving the accuracy of grounding fault identification and positioning in complex scenarios; designed an encryption algorithm Elastic management strategy, realizing the smooth switching of multiple encryption algorithms and meeting the requirements of real - time Service encryption security authentication. At present, the product has successfully gone abroad and been exported to the Middle East market, showing the excellent technical strength of Chinese power equipment on the international stage.
The Substation Electrical Energy Acquisition Terminal (WFET - 2000 Type) realizes the domestic substitution of software and hardware, and fully adapts to the needs of the Construction of new power systems and the large - scale access of new energy. Focusing on the development trends such as power spot trading with new energy as the main body, distributed energy access and source - network - load - storage collaboration, it has successfully solved the technical problems such as high - frequency acquisition, high - Precision clock synchronization and rapid recovery of communication anomalies. The terminal uses a high - performance hardware platform based on domestic devices and a domestic operating system to realize the independent control of the system; innovatively designs a three - level clipping anti - misconnection circuit for the RS - 485 bus, which can withstand the 420V power frequency misconnection between any two wires; proposes an asynchronous serial port IRIG - B code analysis method to achieve microsecond - level accurate time synchronization and ensure the accuracy of the time stamp of metering data; constructs a multi - modal elastic acquisition architecture, integrates dynamic task sharding and feedback fault - tolerance mechanisms, and supports multi - channel concurrent meter reading and communication anomaly self - healing to ensure the efficiency and stability of data acquisition in complex environments. The overall technical level has been identified as domestic leading by experts.
The international/domestically leading recognition of these two technological achievements not only represents the culmination of Willfar Information's technical accumulation but also signifies that Chinese power equipment enterprises have evolved from "followers" to "rule-makers." During this critical phase of global energy transition, Willfar Information is wielding technological innovation as its pen to script a narrative of China's high-end manufacturing competitiveness on the global stage.
In the future, Willfar Information will continue to take the development strategy of "Connecting the World with IoT, Linking the Future with Chips", continue to increase R & D investment, serve the construction of global new power systems, digital transformation of industry and commerce, and intelligent management of household energy, actively participate in the technological progress of the industry and the green and low - carbon transformation of energy, and continue to create value for customers, employees, investors, the industry and society.
