【摘要】：智能电网属于一类新型的电网,它高度集中了原本的信息、通信、计算机以及测量的技术。本课题以同步测量系统为研究对象,重点研究以下几个方面：(1)同步向量测量算法研究：理论上同步相量测量系统的测量装置可以做到同步测量,但是实际应用中是有误差的。本课题将对传统的算法进行详细剖析,对其实用性进行分析,力求提出一种改进算法,使得所测相量和频率的精度提高。(2)PMU的配置方案：传统的PMU配置方案在系统中只考虑配置PMU装置,以改善状态估计精度为目的,借用SCADA系统完全可观测概念,使整个系统完全可观察,并用禁忌搜索法求得。本文的组织结构：绪论部分首先就课题研究的背景及意义进行阐述；对同步向量测量算法做出研究；分析多种广泛采用的PMU最优配置方法,提出了基于搜索禁忌的PMU最优配置算法,并在几种典型节点系统中对算法的正确性和可靠性进行了验证；智能电网的PMU配置方案研究,详细的就PMU的配置方案以及优化配置的算法进行介绍,就智能电网中,同步相量测量传输方式加以阐述。最后是结论部分。本文以同步相量测量与传输的几个关键问题作为研究对象,以适应智能电网的要求作为指导,预期在以下方面突出创新性。比较各种同步向量测量算法在测量精度和实时性方面的优劣,力求改进算法,突出实用性；PMU装置中考虑PMU与现有SCADA系统相补充,发挥现有SCADA系统的优势,节约投资,突出实用性；同步相量测量通信系统设计中采取数据压缩的方法具有创新性。
[Abstract]:Smart Grid is a new type of power grid, which is highly concentrated on information, communication, computer and measurement technology.In this paper, the synchronous measurement system is taken as the research object, and the following aspects are emphatically studied: the synchronous vector measurement algorithm is studied in the following aspects: in theory, the synchronous phasor measurement system can achieve synchronous measurement, but there are errors in practical application.This topic will analyze the traditional algorithm in detail, analyze its practicability, and try to put forward a kind of improved algorithm.In order to improve the precision of phasor and frequency measurement, the traditional PMU configuration scheme only considers the configuration of PMU devices in the system. In order to improve the accuracy of state estimation, the SCADA system can be used as a completely observable concept.The whole system can be observed completely and obtained by Tabu search method.The organizational structure of this paper: in the introduction part, the background and significance of the research are described; the synchronous vector measurement algorithm is studied; and many widely used PMU optimal configuration methods are analyzed.The PMU optimal configuration algorithm based on search Tabu is proposed, and the correctness and reliability of the algorithm are verified in several typical node systems.The configuration scheme of PMU and the algorithm of optimizing configuration are introduced in detail, and the transmission mode of synchronous phasor measurement in smart grid is described.The last part is the conclusion.This paper takes several key problems of synchronous phasor measurement and transmission as the research object and adapts to the requirements of smart grid. It is expected to highlight innovation in the following aspects.This paper compares the advantages and disadvantages of various synchronous vector measurement algorithms in measuring accuracy and real time, and tries to improve the algorithm, highlight the consideration of PMU and the existing SCADA system in practical PMU devices, give full play to the advantages of the existing SCADA system and save investment.The method of data compression in the design of synchronous phasor measurement communication system is innovative.
