基于NI CRIO平台的智能变电站电抗器保护模拟装置设计

摘要电抗器保护的装置属于一种继电保护装置。它对电力系统是否可以全稳定运行起了很大影响。随着自动化技术的日益发展，电力系统许多控制操作日趋高度自动化。智能变电站对于二次回路的改进是显著的，且是原理性的。面对全新的二次回路，传统保护装置数据传输模式被打破，需要设计适合智能变电站的保护装置。CRIO是一个硬件的平台，它可以实现嵌入式控制和采集硬件。CRIO平台内置的Labview功能有一千多种，可以用来创建多线程嵌入式系统，能够实现分析、数据记录、通信和实时控制等功能。
本论文首先重点研究并且分析了电抗器的纵差动保护和零序差动保护的基本原理。然后基于NI CRIO平台，利用Labview软件实现了对电抗器保护模拟装置的软件设计，对智能变电站电抗器保护装置的基本功能进行模拟。实现了差动保护，零差保护，以及后备保护的主要功能，并对所设计的程序进行了仿真测试。仿真的结果表明程序的逻辑正确。19572

Title   Based on NI CRIO platform of intelligent substation reactor protection analog device design
Abstract
Reactor protection device belongs to a kind of relay protection device. It to whether can the stable operation of power system played a very big effect.With the development of automation technology, a lot of control power system is highly automated operation. Intelligent substation secondary loop over traditional improvement is significant, and the rational. In the face of new secondary loop, the traditional protection data transfer mode is broken, need to design for intelligent substation protection device. CRIO is a platform, it can realize embedded control and acquisition hardware. CRIO platform there are more than one thousand built-in Labview function, can be used to create a multithreading embedded system, can realize analysis, data record, communication and real-time control, and other functions.
This paper first analyses the reactor of longitudinal differential protection and the basic principle of zero-sequence differential protection. Then based on NI CRIO platform, using Labview software to achieve the software design for the reactor protection simulation device, on the basic function of intelligent substation reactor protection device simulation. Realizing the zero differential protection, longitudinal differential protection, and the main function of backup protection, Simulation is conducted and the program. The simulation results show that the program logic is correct.
