摘　　要：用于工业园区、油气开发等的孤立电力系统广泛存在,其组网脆弱、灾后完全停产等问题严重影响了系统生产、运行效率。针对孤立电网的灾后恢复策略开展了研究。以海上油气开发为例建立了系统生产全流程模型,提出了负荷恢复度的概念并建立了产量与各类负荷关系的多元函数。针对孤立电网负荷恢复过程的电压与频率暂态稳定性进行了分析,将分析结果以构建约束条件的方式纳入优化模型。提出了用于确定负荷恢复顺序的系统灾后恢复模型并应用贪心算法进行求解。算例结果验证了所提出的模型及方法的有效性。Isolated power systems are widely used in industrial parks,oil and gas development,etc.The problems such as fragile networking and complete shutdown after disasters seriously affect the production and operating efficiency of the systems.The post-disaster recovery strategy of isolated power grid is studied.The whole production process model of system is established by taking offshore oil and gas development as an example,the concept of load recovery degree is proposed,and the multivariate function of the relationship between production and various loads is established.Then,the transient stability of voltage and frequency during the load recovery process of the isolated power grid is analyzed,and the analysis results are incorporated into the optimization model by constructing constraints.A post-disaster recovery model for determining the load recovery sequence is proposed and solved by the greedy algorithm.Case results verify the effectiveness of the proposed model and method.
