【摘要】:傳統(tǒng)的交流配電網(wǎng)面對日益增長且密集的用電負荷,面臨著供電走廊緊張、電能質量問題突出、分布式能源接入以及電能供應可靠性、經(jīng)濟性等方面的巨大挑戰(zhàn)。研究資料表明,基于直流的配電網(wǎng)具有提高供電容量、減小線路損耗、改善用戶側電能質量、隔離交直流故障,以及可再生能源靈活、便捷接入等一系列優(yōu)點,因此直流配電以其優(yōu)勢獲得了廣大研究者的青睞,國內(nèi)對直流配電網(wǎng)的研究主要集中在穩(wěn)態(tài)分析、故障分析與保護、穩(wěn)定運行控制、電能質量控制等方面。建立專門的直流配電實驗系統(tǒng),可以為直流配電技術的研究提供仿真與試驗研究,推動直流配電技術的發(fā)展。 在本文中,對適應于分布式能源接入的直流配電模擬實驗系統(tǒng)進行了研究。首先本文整理并歸納了直流配電系統(tǒng)以及動模試驗系統(tǒng)的基本概念,對直流配電網(wǎng)的拓撲母線結構、電壓等級、控制與保護進行了簡述和總結。另一方面,對建立動態(tài)模擬試驗系統(tǒng)的相似原理和模擬比以及常見的模型建立做了簡要的概述,為后續(xù)直流配電模擬實驗系統(tǒng)的建立提供理論基礎和支持。 在此基礎上,本文分析了直流配電模擬實驗系統(tǒng)的結構組成和功能,確定由物理模擬(動態(tài)模擬)與數(shù)字模擬(仿真模擬)兩部分構成,可開展直流配電網(wǎng)拓撲結構、系統(tǒng)控制與保護等相關技術的建模仿真與實驗研究,以及變流器、直流斷路器等直流配網(wǎng)關鍵設備的功能性試驗研究。基于此目標,本文對仿真模擬平臺的軟件設備選擇做了對比研究,確定PSCAD和RT-LAB作為純數(shù)字仿真和實時仿真軟件。接著對模擬實驗系統(tǒng)中的主要部分,動態(tài)模擬實驗系統(tǒng)的拓撲結構、電壓等級等參數(shù)做了研究和設計,并對其中主要的模型(包括分布式電源、儲能裝置、負荷、配電線路、直流變壓器、直流斷路器等)在實驗室中的模擬做了詳細的研究和論述。此外,還對實驗系統(tǒng)的測量控制與監(jiān)控系統(tǒng)以及設備檢驗做了分析和設計。最后,利用模擬仿真的純數(shù)字仿真軟件對典型的基于分布式電源的直流配電系統(tǒng)進行了簡單的建模仿真。
[Abstract]:The traditional AC distribution network faces the increasing and intensive power load, the shortage of the power supply corridor, the prominent power quality problems, the distributed energy access and the reliability of the power supply. The research data show that the distribution network based on DC can improve the power supply capacity, reduce the line loss, improve the power quality on the user side, and isolate the AC / DC fault. As well as renewable energy flexible, convenient access to a series of advantages, so DC distribution for its advantages have been favored by the majority of researchers, the domestic research on the DC distribution network is mainly focused on the steady state analysis. Fault analysis and protection, stable operation control, power quality control and other aspects. The establishment of a special DC distribution experiment system can provide simulation and experimental research for DC distribution technology. Promote the development of DC distribution technology. In this paper, the DC distribution simulation experiment system suitable for distributed energy access is studied. Firstly, the basic concepts of DC distribution system and dynamic model test system are summarized. The topology bus structure, voltage grade, control and protection of DC distribution network are briefly described and summarized, on the other hand. This paper gives a brief overview of the similarity principle, simulation ratio and common model establishment of the dynamic simulation test system, which provides the theoretical basis and support for the establishment of the subsequent DC distribution simulation experiment system. On this basis, this paper analyzes the structure and function of DC distribution simulation experiment system, which is composed of physical simulation (dynamic simulation) and digital simulation (simulation simulation). It can be used for modeling, simulation and experimental research on topology structure of DC distribution network, system control and protection, and converter. Based on this goal, this paper makes a comparative study on the software equipment selection of the simulation platform. PSCAD and RT-LAB are chosen as pure digital simulation and real-time simulation software. Then, the topology of the dynamic simulation experimental system is given to the main parts of the simulation experiment system. The parameters such as voltage level are studied and designed, and the main models (including distributed power generation, energy storage device, load, distribution line, DC transformer) are studied and designed. The simulation of DC circuit breaker in the laboratory is studied and discussed in detail. In addition, the measurement control and monitoring system and the equipment inspection of the experimental system are analyzed and designed. The simple modeling and simulation of a typical DC distribution system based on distributed power supply is carried out by using the pure digital simulation software of simulation.
