The venture capital group directly invested in the company Yihui Information, and the SylixOS system has been successfully applied in the ultra-high voltage direct current transmission project.

Recently, the Nanjing Innovation Investment Group (hereinafter referred to as "Investment Group") directly invested in Beijing Yihui Information Technology Co., Ltd. (hereinafter referred to as "Yihui Information"). The SylixOS system has been successfully applied in the "Longdong-Shandong ±800kV UHVDC Transmission Project". This project can meet the reliable power delivery needs of the large integrated energy base in the Longdong area, promote economic development in the revolutionary old areas of Longdong and surrounding regions, while also meeting the load growth demands of the Shandong power grid in the southwestern and northwestern regions, advancing the transformation of the development mode of the Shandong power industry, optimizing the energy structure, increasing the proportion of green energy, and improving the overall safety and stability of the system and power supply reliability.

The Longdong-Shandong ±800kV UHVDC transmission project is the first to apply the "fully domestically produced DPS-5000G DC transmission control protection system", which was designed and developed by XJ Electric based on the Yihui large embedded real-time operating system SylixOS. It achieves computing power aggregation, strong computing capability, high real-time performance, with a minimum task cycle of 10us, matching the highest level in the industry. This project is also the first UHVDC transmission project in the country to use a domestically produced operating system.

Yihui Information was established in 2015 and is a leading domestic embedded operating system service provider, focusing on providing industry users with independently controllable embedded real-time operating systems and related technical services and product solutions. It has independently developed the first large-scale domestic real-time operating system SylixOS, which is also the only real-time operating system in the country that can match VxWorks and QNX in terms of functionality and performance. The power industry is a key market area for Yihui Information, and its fully independent technical base has been applied in various critical power equipment such as thermal power DCS controllers, nuclear power DCS, hydropower PLC, wind power PLC, thermal protection devices, relay protection, DC control and protection, protection measurement and control, distribution terminals, and fault recording. Currently, Yihui Information, in collaboration with partners, has won honors such as the "2020 China Machinery Industry Science and Technology Progress Award First Prize", "China Electric Power Enterprise Federation Electric Power Science and Technology Innovation First Prize", and "Shenzhen Science and Technology Award First Prize for Scientific and Technological Progress".

The Investment Group participated in Yihui Information's Series C financing in July 2023. This round of financing was led by State Investment and Development Corporation, with the Nanjing Municipal Talent Fund Phase II - Nanjing Zijinshan Talent Innovation and Entrepreneurship Investment Fund, managed by the Investment Group, co-investing 10 million yuan. Power safety is related to the national economy and people's livelihood, and is an important guarantee of national security, requiring high levels of technological independence and controllability. The relevant person in charge of the Investment Group's investment department stated that the core team of Yihui Information has been deeply engaged in the industry for many years, and the Investment Group is optimistic about the technical level of founder Han Hui, believing that under Han Hui's leadership, Yihui Information will continue to develop and innovate in the future, becoming a leader in the domestic embedded operating system field and continuously promoting the application of the company's products in the energy and power industry.
