【摘要】 本论文对大庆油田电力仿真培训系统进行了系统的分析,重点开展了建模方法的研究。 1.分析了大庆电力系统潮流变化状况,讨论了静态模型与动态模型,建立了晶闸管控制的电力系统潮流模型和算法。 2.提出了将人工智能应用于电力仿真培训系统的思路,介绍了一个智能决策接口的组成和它的数据组织形式。 3.根据复杂大系统模块化建模思想,提出了适用于大庆油田电力系统建模的模块划分和综合原则。基于神经网络的非线性系统建模方法,开展了利用Elman动态神经网络与机力模型互补的建模研究。 4.利用动态连接库(DLL)技术,按照各种保护的保护原理,建立了电力系统继电保护的保护模型库。以故障计算为基础,以整定值和延时时间为判据,采取提高实时性的有效措施,按时间段扫描全部保护。 5.从继电线路功能仿真和验证的角度出发,建立了继电元件和线路的模型,并在此基础上设计了功能仿真算法,从而完成了继电线路功能仿真与验证系统。 本文的研究成果已开始应用于大庆油田电力仿真培训系统的实际工程中,具有理论意义和工程意义。

【Abstract】 The systemic analyse is made for the imitated training of the electric power in Daqing oil field. The research of modeling method is developed as emphases.1.It analyzes the status of tidal current change in Daqing electric power system, discusses static state model and dynamic model, and establishes the tidal current model of Daqing electric power system and arithmetic which are controlled by crystal brake tube.2.It puts forward the idea that is applied the artificial intelligence to the imitated training system of the electric power, and introduces a compose of brainpower decision-making interface and its organizational form for data.3.In the base of the modularized modeling idea with complicated big system, it puts forward principle of plotted and integrated module which is the same with modeling in the electric power system of Daqing oil field. Basing on the non-linear system’s modeling method of NN, it develops the modeling research that utilizes the mutual makeup in Elman dynamic NN and invigorative model.4.1t sets up the protective model warehouse of the electric power system’s followed-electricity protect with using DLL technique, according to protective principle of every protect. In the base oftrouble-calculating and the criterion with full fixed value and delayed time, it adopts the efficient measure improving real time, and it scans all protect on schedule.5.Leaving the functional imitation of followed-electricity circuitry and validating angle, it establishes followed-electricity component and circuitry model, and it plans method of the functional imitation on the base of it. Consequently, it finishes the system of the functional imitation of followed-electricity circuitry and validation.The researched production has applied to the practical engineer in the imitated training of the electric power in Daqing oil field.
