基于风险地图方法的特高压工程大规模建设潜在风险评价及防控

Potential Risk Assessment and Prevention of Large-scale UHV Construction Projects Based on Risk Map Methods

随着我国输电技术的成熟,特高压输电技术在优化能源资源配置、大气污染防治、实现人类可持续发展方面展现了独特优势,特高压电网在我国的工程实践已经进入快速、规模化发展的新阶段。目前国家电网公司已经建成投运"三交四直"特高压工程,在建"四交五直"特高压工程(包括纳入大气污染防治计划的"四交四直"工程),工程建设实践从早期的一条线发展到多条线同步建设的新阶段,在大规模建设背景下对关键资源和关键管理流程带来巨大挑战。从关键管理流程出发,基于风险地图方法,在研究识别关键流程风险的基础上开展风险量化评价,并基于风险评价结果采用研究构建的"管理三要素"框架提出风险防控措施建议。通过量化评价,进一步明确特高压电网大规模建设过程中需要高度关注的重点风险,为未来加强风险防控、确保大规模建设目标的实现指明方向。

As Chinag power transmission technology matures, UHV transmission technology has shown the unique advantages in optimizing energy resources, controlling air pollution, and achieving sustainable human development. So UHV grid engineering practice has entered a rapid, large - scale development of new stage in our country. At present, State Grid Company of China （SGCC） has built and put into operation ＂three AC four DC＂ UHV projects, and they are constructing ＂four AC five DC ＂ UHV projects （ including ＂ four AC four DC ＂ projects which are involved in national air pollution control program）, and the construction practice developed from earlier one line to a new stage of simultaneous construction of multiple lines. Under the background of large - scale construction, there are huge challenges for key resources and critical management processes. In this paper, starting from the key management processes, based on the risk map approach, on the basis of identifying the key processes risk, we carried out quantitative assessment of the risks. We proposed risk control measurements based on the ＂three elements of management＂ framework formulated and the results of risk assessment. Through quantitative evaluation of risk, we clarified the attention focused on large - scale UHV grid construction, and it pointed out the direction for the future to strengthen risk prevention and control and ensure the goal of large - scale construction.
