【摘要】 在电力市场环境下为了保障电力系统安全、稳定、有序运行，将电厂运行和管理水平与月度发电量计划挂钩。在相关系统的基础上，根据《浙江电网统调发电厂调度运行管理细则》的要求，本论文设计并研究了浙江电网统调电厂调度运行考评系统。考评系统是电力调度运行和电力市场运营的重要组成部分，包括执行调度发电计划考评、机组AGC考评、机组一次调频考评、电压和无功功率考评、机组可用性考评、设备检修管理考评六项内容，还包括资源管理、免考管理等模块。最终形成考评结果，并通过Web方式实时发布。本论文详细论述了考评系统的软硬件体系结构设计、业务设计、系统的特点及业务创新点。通过对现场实际运行情况的调研和大量考评数据及相关文献的分析，重点对机组AGC和机组一次调频等常用的考评算法做出了改进，对电压和无功功率管理的现行考评规则提出建议，突出考评的公平性和实用性，并利用部分原始数据进行仿真。考评系统业务流程复杂，所以本系统引入工作流，并设计相应的业务流程模型。最后本论文调研了考评系统的运行现状，分析了运行的效益，并对考评系统架构、图形显示的改进及发展趋势做出了展望。更多还原

【Abstract】 In order to make sure the power system to operate safely, steadily and orderly in the environment of electricity market, we connect the operation and management level with the monthly generating quantity plan. Based on the related systems and management rules for grid-connected power plant, this paper designs and researches the assessment system for grid-connected power plant’s operation management. Assessment system is the important component of the dispatching operation and the electricity market management of power system. The system includes generating quantity operation, automatic generation control, primary frequency control and so on. The system also includes resource management, exemption management and so on. Finally the system publishes the evaluation results through web.This paper discusses the hardware and software system architecture design, business design, the system’s features and business innovations of the assessment system in detail. Based on investigation of operation situation and analysis of extensive data and literature, the paper makes improvement and recommendations for the existing or common algorithms of automatic generation control, primary frequency control and so on, emphasizes the fairness and simulates practicality based on the primitive data. As the Business process is complex, the system inducts the workflow and designs relational business process model. Finally the paper investigates the status, analysis the operational efficiency of the system and describes the development prospect of system structure, graphic displaying and so on.更多还原
