【摘要】：电力供需平衡关系的长期动态均衡是电力工业可持续发展的重要前提,也是国民经济持续高速发展的重要条件。目前,电网企业对电力供需平衡的要求日渐突出,电网企业的供需平衡调整、负荷预测、发电备用分析等工作逐渐发挥着更重要的作用,特别是目前电网负荷高速增长的情况下,因电源侧供应问题,电网企业局部地区不得已采用避峰限电,甚至拉闸限电等措施以保证电网运行的安全、稳定运行。本文主要通过对发电厂运行历史数据和电网当前运行情况的分析,设计实现了一个供需平衡技术支持系统,整合现有电力电量资源,实现供需平衡分析及风电、火电参与电网调度优化辅助决策分析,完成电网企业全网供需形势的预测。该系统采用多层B/S技术架构,开发语言及技术采用Java语言,实时进行数据收集传输、管理、接口、发布等。系统主要包括供需平衡预测、负荷预测考核、风电接纳能力预测分析、风电参与调峰评估、设备实时及历史追溯、发电设备检修计划关键算法的研究与供需平衡、发电进度、火电机组等主要功能的实现。该系统整合了电网调度各级单位和各专业、部门间工作,实际运行情况表明,系统实现了提高电网供需平衡工作的效率和水平,达到优化电量分布,动态掌握供需平衡的目的。在电网企业中,供需平衡关系技术支持系统的建设起到了调节各种电力资源顺畅流动和优化配置的方向和强度。论文首先介绍背景、系统的开发目的和课题的提出,并给出论文结构安排;然后,论文详细介绍系统所采用的关键算法;系统设计部分,首先介绍系统的总体设计,然后对总体设计划分好的模块设计进行详细介绍,最后介绍系统的数据库设计,给出设计的部分E-R图和数据库表;系统实现部分,首先详细介绍各个模块的具体实现。系统测试部分,详细介绍系统的集成以及给出测试结论;最后,对本文工作做了总结,并进行了下一步工作展望。
[Abstract]:The long-term dynamic equilibrium of power supply and demand balance is an important prerequisite for the sustainable development of electric power industry and also an important condition for the sustained and rapid development of the national economy. At present, the demand of power supply and demand balance for power grid enterprises is increasingly prominent. The adjustment of supply and demand balance of power grid enterprises, load forecasting, power generation standby analysis and other work gradually play a more important role, especially in the current situation of high-speed growth of grid load, because of the power side supply problems. In order to ensure the safe and stable operation of the power network, some measures such as avoiding the peak and limiting the power supply, even pulling the switch, are used to ensure the safe and stable operation of the power network. This paper mainly analyzes the historical data of the operation of the power plant and the current operation situation of the power network. A technical support system for balance of supply and demand is designed and implemented, which integrates the existing power resources, realizes supply and demand balance analysis and wind power, and thermal power participate in the auxiliary decision analysis of power grid dispatching optimization. The system adopts multi-layer B / S technology architecture, the development language and technology adopt Java language, real-time data collection, transmission, management, interface, release and so on. The system mainly includes supply-demand balance prediction. Load forecasting assessment, wind power acceptance forecasting analysis, wind power participation in peak-shaving assessment, real-time and historical tracing of equipment, research on key algorithms of maintenance plan for generating equipment, balance between supply and demand, power generation progress, The realization of main functions such as thermal power units. The system integrates all levels of power grid dispatching units and professional, inter-departmental work. The actual operation shows that the system can improve the efficiency and level of power supply and demand balance work. To achieve the purpose of optimizing the distribution of electricity and dynamically grasping the balance of supply and demand. The construction of the technical support system of the balance between supply and demand has played a role in regulating the smooth flow of various power resources and the intensity of the optimal allocation. Firstly, the background, the purpose of the system development and the proposal of the subject are introduced in this paper, and the structure of the paper is given. Then, the paper introduces the key algorithms of the system in detail, the system design part, first introduces the overall design of the system, then introduces the module design of the overall design division in detail, finally introduces the database design of the system. The part of E-R diagram and database table is given, the realization part of the system, the detailed implementation of each module, the part of system test, the integration of the system and the test conclusion are introduced in detail. Finally, the work of this paper is summarized. The future work is prospected.
