基于NICRIO平台的智能变电站核相仪设计

核相是电力生产中经常遇到的一项工作，主要用于电网改造升级及电网合并时对并网各线相位的检查。核相错误会导致电网的不稳定，容易引起连锁的灾难性的结果，因此核相的任务正变得越来越重要。
与传统变电站相比，智能变电站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，传统的核相方法难以实现，需要设计适合智能站的核相方法。本文首先分析了智能变电站及 IEC 61850 标准，将智能变电站与传统变电站进行了比较。然后基于 NI CRIO 平台进行分析，使用 NI CRIO 硬件平台进行了系统的总体设计，同时对 SV 报文的结构进行了分析，使用 LabVIEW 编写了报文解析程序。最后列举了一些常用的电力系统核相方法，使用 LabVIEW 编写了相应的程序进行了测试，并且对测试结果进行了分析。21132

Title Design of Phase Test Meter for Intelligent Substation Based on NI CRIO Platform
Abstract
Phase test is a work often encountered in product of electricity, mainly
for checking phase of the cable network when upgrading the grid and merging
different grids. If there is something wrong with the phase test, it may
result in an unstable power grid, easily leading to a chain reaction of
catastrophic results. So the task of phase test is becoming more and more
important.
Compared with the conventional substation, the improvements of the
secondary circuit of the intelligent substation are notable, and they are
schematic in nature. Facing the new secondary circuit, the traditional
phase test method is difficult to realize, so we need to design phase test
method which is suitable for intelligent substations.
This dissertation analyzes the smart substation and the IEC 61850 standard,
and compares the intelligent substation with conventional substation. Then
it makes an analysis based on NI CRIO platform and designs the overall
system using NI CRIO hardware platform, while analyzing the SV packet
structure and writing a message-analysis program using LabVIEW. Finally,
some commonly used method for phase test have been exampled,and the
corresponding program have been written using LabVIEW. The programs have
been tested and the test results have been analyzed.
