中文摘要：
针对中期火电开机优化的特点,建立了应用于不同实际需求的三种优化模型：基于电量差别计划的等利用小时数模型、等利用率模型和能耗最小模型,同时结合逐步优化算法（POA）算法搜索能力强、收敛速度快等特点,给出了模型的统一求解流程。采用可扩展的模型接口方式、基于Fork/Join框架的多核并行优化、基于MVC模式手动开机及异步优化等关键技术设计开发了中期火电开机优化系统,并成功应用于云南电网实际运行。最后以云南电网9座火电站27台机组的计算结果为例,分析验证了模型的灵活性、合理性及系统的实用性。
英文摘要：
Aiming at the characteristics of mid-term optimal operation of thermal power,three kinds of models including equivalent utilization hours model,equivalent utilization ratio model and minimum energy consumption model based on electricity difference plan are established for different actual demands.This paper proposes a unified strategy which combines the characteristics of powerful global search and fast convergence of Progressive Optimality Algorithm （POA） to solve the models.Furthermore,it designs and applies the system of mid-term optimal operation of thermal power in Yunnan Power Grid successfully based on several key technologies such as extensive model interface,multi-core parallel optimization of Fork/Join framework,manually startup of MVC pattern and asynchronous optimization.Finally,the models and the system are analyzed and verified by 27 units of 9 thermal power plants in Yunnan Power Grid.The result shows that the models are flexible and reasonable and the system is practicable.
