摘要/Abstract

摘要：

台风等极端天气频发,给海上风电机组检修计划的制定带来了挑战。一方面,定期检修不能及时应对台风等恶劣天气的影响,而状态检修随机的检修时段不便于实际操作;另一方面,海上风电机组定期检修计划需要合理考虑多方面因素。因此,考虑台风影响,提出双层检修优化策略:上层定期检修优化以检修成本、海上风电系统送出能力、受端电网可靠性三方面的指标综合评分为优化目标;下层状态检修优化以检修成本最小为目标,在上层定期检修优化之上优化安排状态检修计划。之后通过算例对所提双层检修策略进行对比评估。算例表明,与定期检修和状态检修相比,所提双层检修计划能够在检修成本增幅不大的情况下,有效提高系统可靠性和海上风电系统送出能力。

Abstract:

Frequent occurrences of extreme weather events, such as typhoons, pose challenges to the development of maintenance plans for offshore wind turbines. Periodic maintenance cannot promptly deal with the impact of severe weather such as typhoons, while condition-based maintenance is infeasible for practical operation owing to random maintenance periods. Periodic maintenance plans for offshore wind turbines require the careful consideration of various factors. Therefore, considering the impact of typhoons, this paper proposes a two-level maintenance optimization strategy: the upper level periodic maintenance optimization considers the comprehensive score of the maintenance cost, transmission capacity of offshore wind power systems, and reliability of the receiving-end grid as optimization objectives; the lower-level condition-based maintenance optimization considers the minimum maintenance cost as the goal and optimizes the arrangement of the condition-based maintenance plan above the upper-level periodic maintenance optimization. Subsequently, an example is provided to compare and evaluate the proposed two-layer maintenance strategy. The example shows that, compared with periodic maintenance and condition-based maintenance, the proposed double-layer maintenance plan can effectively improve the reliability of the receiving-end grid and the transmission capacity of offshore wind power systems with a small increase in maintenance costs.
