On October 15, 2022, the scientific and technological achievement of "SCADA system development and refined oil pipeline application" jointly completed by South China Branch of National Petroleum Pipeline Network Group Co., Ltd. and Hangzhou Hollysys Automation Co., Ltd. successfully passed the technical achievement appraisal organized by China Petroleum and Chemical Automation Application Association. The appraisal committee believes that the overall technology of this achievement has reached the international advanced level, among which the trusted computing technology of the whole life cycle of the industrial control system, the dual-system parallel and the deterministic real-time communication protocol technology based on the concurrent master-slave polling mechanism are at the international leading level, and unanimously agreed to pass the appraisal of scientific and technological achievements.
The domestic long-distance oil and gas pipeline control system has long adopted foreign SCADA system, and the core control technology is highly dependent on foreign countries, the cost remains high, and the supply of spare parts is not timely, which seriously affects the safety and stability of production.
The South China Branch of National Petroleum Pipeline Network Group Co., Ltd. regards the country's energy security as its corporate responsibility and mission, and has established the "Research Working Group on the Localization of Core Technology of Refined Oil Pipelines", with a number of experts and technical backbones forming a major scientific and technological research team. After a number of technical research and cooperation, and finally cooperated with Hangzhou Hollysys Automation Co., Ltd. to form a "SCADA system development based on independent chips and operating systems and refined oil pipeline application" research and development team, through the efforts of both parties, the research results have been successfully applied in Zhuhai Station and Zhongshan Station of South China National Pipeline Network Company from August 30, 2021 to September 30, 2022, and the system runs stably and reliably. The results of commissioning show that the system has surpassed similar foreign products in terms of function, performance and reliability, and can be completely replaced by localization.
This achievement has obtained 10 authorized invention patents, registered 10 national software copyrights, and formulated 4 national standards.
Hollysys' SCADA system for refined oil pipelines based on independent chips and operating systems is a 100% domestically developed control system with independent intellectual property rights, with the protection function of trusted computing and endogenous information security, and the microkernel technology can realize cross-platform operation, with advanced technology, realizing that the SCADA system is completely independent and controllable, safe and credible, reducing engineering costs, and has formed a new core competitiveness in the field of oil and gas pipelines, which will greatly improve the infrastructure safety level of oil and gas pipelines. It plays an important role in ensuring the security of national oil and gas energy.
