摘 要

随着时代的慢慢发展,特别是进入21世纪的今天,我们国家不管是经济、文化,还是其他方面都发生了突飞猛进的进步。而这些成就的背后都是靠着我们国家强有力的电力系统做支撑。而变电站作为电力系统中的关键环节起着重要的作用。变电站主要可以分为两部分,第一个部分指的是一次设备,第二部分指的是二次设备。第一部分一次设备是用来产生电能,接着输送电能,最后分配电能的设备。第二部分二次设备是用来监测一次设备运行状况,来保护一次设备的设备。

而其中计量设备是二次设备的重中之重,它关乎整个二次设备乃至整个变电站的工作状态和效率。长期以来,传统的计量设备存在着误差偏大、电能量信息采集不及时的问题,这对社会经济效益产生了显著的影响。慢慢的伴随着科技的进步,整个世界和国家的经济工业快速发展,这对电力工业系统产生了巨大的挑战。过去以往的变电站体现出了其局限性,难以满足当前的需求。

在最近一二十年时间内,我国开始大力发展智能电网,并且将此作为战略目标。整个国家大规模投入建设智能变电站。正是这一系列措施的实施之下,作为智能变电站的重要组成部分的数字化计量系统也开始慢慢发展。在此之前国内外已经提出了很多关于数字化计量设备的解决方案。这其中基于IEC61850的智能站数字化计量设备成为主流的解决办法。本文主要就此项解决方案的不同模块利用visio绘图软件以及公式编辑器等工具对其进行深入剖析,并且研究数字化电能量采集终端的解决方案。这对电力系统和社会经济生活具有重要的意义。

Abstract

With the gradual development of the times, especially in the 21st century, our country has made rapid progress in terms of economy, culture and other aspects. Behind these achievements is our country's powerful power system. The substation plays an important role as a key link in the power system. The substation can be divided into two parts, the first part refers to the primary equipment, and the second part refers to the secondary equipment.

  Among them, the measurement equipment is the top priority of the secondary equipment, which is related to the working status and efficiency of the entire secondary equipment and even the entire substation. For a long time, the traditional measurement equipment has the problems of large errors and untimely collection of electrical energy information, which has had a significant impact on social and economic benefits. With the progress of science and technology, the economic and industrial development of the entire world and countries has developed rapidly, which has created huge challenges for the power industry system. In the past, substations in the past have shown their limitations and it is difficult to meet current needs.

  In the past decade or two, China has begun to vigorously develop smart grids, and regards this as a strategic goal. The entire country has invested heavily in the construction of smart substations. It is under the implementation of this series of measures that the digital metering system, which is an important part of smart substations, has begun to develop slowly. Prior to this, many solutions for digital metrology equipment have been proposed at home and abroad. Among them, the digital measurement equipment of intelligent stations based on IEC61850 has become the mainstream solution. This article mainly analyzes the different modules of this solution using tools such as visio drawing software and formula editor, and studies the solutions of digital electric energy collection terminals. This is of great significance to the power system and social and economic life.
