【摘要】：為滿足智能變電站建設(shè)和發(fā)展的需求,需開發(fā)一種可供測試、評估、檢驗的仿真測試系統(tǒng),實現(xiàn)對智能電子設(shè)備或智能組件的功能和性能的整體測試。本文開展對智能變電站分布測試系統(tǒng)的研究,研制一種基于無線通信技術(shù)的智能變電站分布測試系統(tǒng)中的控制器硬件電路。 本文主要針對智能變電站的技術(shù)特征,在現(xiàn)有的數(shù)字化測試裝置基礎(chǔ)上,提出智能變電站二次設(shè)備分布測試系統(tǒng)的概念,給出測試的方法及流程,研制一種新型的智能變電站測試裝置。將WIFI無線局域網(wǎng)技術(shù)融合到了智能變電站分布測試系統(tǒng)中,實現(xiàn)計算機與控制器的通信聯(lián)系,利用無線通信技術(shù)使得系統(tǒng)控制器安放位置和測試方便、靈活。從智能變電站分布測試系統(tǒng)出發(fā),分別研究了分布式測試系統(tǒng)的技術(shù)路線和工作原理及其組成。分析了無線通信在智能變電站分布測試系統(tǒng)中的應(yīng)用,具體研究了基于WIFI的無線功能模塊的硬件制作和實現(xiàn)方法。通過對分布測試系統(tǒng)的工作流程的詳細(xì)分析,最終以220KV智能變電站為例,闡述了分布式測試系統(tǒng)的應(yīng)用情況。 實驗表明,基于無線通信技術(shù)的分布式測試系統(tǒng)可以對變電站二次系統(tǒng)技術(shù)性能進行完整檢測,還可以支持智能化變電站之間的聯(lián)合調(diào)試,為智能化變電站現(xiàn)場測試提供了新的技術(shù)手段。
[Abstract]:In order to meet the needs of the construction and development of intelligent substation, it is necessary to develop a simulation test system for testing, evaluation and testing. The function and performance of intelligent electronic devices or intelligent components can be tested as a whole. A controller hardware circuit of intelligent substation distribution test system based on wireless communication technology is developed. According to the technical characteristics of intelligent substation, this paper puts forward the concept of distributed testing system for secondary equipment of intelligent substation based on the existing digital test device, and gives the test method and flow chart. A new type of intelligent substation testing device is developed. The WIFI wireless LAN technology is integrated into the intelligent substation distribution test system, and the communication between computer and controller is realized. The wireless communication technology is used to make the position of the system controller and the test convenient and flexible. Based on the intelligent substation distribution test system, The technical route, working principle and composition of distributed test system are studied, and the application of wireless communication in intelligent substation distributed test system is analyzed. The hardware design and implementation method of wireless function module based on WIFI are studied in detail. Finally, the application of distributed test system is expounded by taking 220KV intelligent substation as an example through the detailed analysis of the work flow of distributed test system. The experimental results show that the distributed test system based on wireless communication technology can test the technical performance of substation secondary system completely, and can also support joint debugging between intelligent substations. It provides a new technical means for intelligent substation field test.
