【摘要】：知行合一是中华传统文化内核的一部分,对现在的人才培养意义重大,对于工程人员更是要完成大量的实验。然而由于各种原因,一般高校的实验设备不是应有尽有的,而且运营、维护和升级的成本高昂。为了更快更好的完成课程要求内的各种实验,利用仿真软件、组态软件及网络技术所构建的虚实结合的仿真实验平台是解决上述问题的重要手段。本文设计了一套基于Simulink仿真平台、组态王组态软件的B/S构架的智能变电站仿真实验平台,该平台包括底层设备仿真平台和上位机组态软件两部分。该平台依托在网络上,用户可以远程登录,登陆后再进行仿真实验,之后并获得相应的结果。以智能变电站仿真模拟运行为例,使用Simulink仿真变电站稳态运行、变压器差动保护、低电压启动的过电流保护、备用保护的算法仿真和其仿真所需电气量的获取。然后通过组态王软件设计变电站监控界面,通过动态数据交互协议实现仿真数据的采集,并用Oracle数据库记录仿真数据、图像及视频等资料,利用组态王的WEB发布功能及Java EE技术将仿真实验平台发布到网络上,这些部分构成一个相对完整的仿真实验平台。用户可以在任何地方在任意时间都可以完成实验项目。为了实现对实时性数据和图片的压缩以及对它们的存档,本文引入了以深度学习的训练方式下的主方法是对图像分成相似的子图形集并压缩的算法来减少数据压缩的时间和空间并提高压缩图像的质量。最后进行软件测试,该平台很好的实现了对智能变电站的仿真的功能和用户操作的可视化,各个功能运行稳定,有较强的实用性和可扩展性。该平台对在线轻量级的低成本的教学用智能变电站仿真实验平台领域进行突破,是对常规的实验操作的有效补充。学生对变电站的了解除了现场参观和观看视频外还有另外的途径,而且对智能变电站的知识了解更完善,加深学生对知识的理解和运用能力。
[Abstract]:The integration of knowledge and practice is a part of the traditional Chinese culture, which is of great significance to the cultivation of talents now, and it is also necessary for engineers to complete a large number of experiments. However, for various reasons, experimental equipment is not available, and the cost of operation, maintenance and upgrade is high. In order to complete all kinds of experiments in the course requirement faster and better, the simulation experiment platform based on simulation software, configuration software and network technology is an important means to solve the above problems. A set of intelligent substation simulation experiment platform based on Simulink simulation platform and configuration software of Kingview configuration is designed in this paper. The platform includes two parts: the bottom equipment simulation platform and the upper computer configuration software. The platform is based on the network, users can log in remotely, then carry on simulation experiment after logging in, and get the corresponding results. Taking the simulation operation of intelligent substation as an example, Simulink is used to simulate the steady operation of substation, transformer differential protection, over-current protection of low voltage start-up, algorithm simulation of backup protection and the acquisition of electrical quantity required by simulation. Then the substation monitoring interface is designed by Kingview software, the simulation data collection is realized by dynamic data exchange protocol, and the simulation data, image and video data are recorded by Oracle database. Using Kingview's WEB publishing function and Java EE technology, the simulation experimental platform is published to the network. These parts constitute a relatively complete simulation experimental platform. Users can complete the pilot project anywhere at any time. In order to compress and archive real-time data and pictures, In this paper, the main method of deep learning training is to divide the image into similar subgraph sets and compress the image to reduce the time and space of data compression and improve the quality of compressed image. Finally, the software test shows that the platform can realize the visualization of the simulation function and the user operation of the intelligent substation, and each function is stable and has strong practicability and expansibility. The platform is a breakthrough in the field of online lightweight, low-cost intelligent substation simulation experimental platform for teaching, and it is an effective supplement to the conventional experimental operation. There are also other ways for students to understand the substation in addition to visiting and watching the video on the spot. Moreover, the knowledge of intelligent substation is more perfect to deepen the students' understanding and application ability of knowledge.
