【摘要】：目前,水電占我國(guó)總發(fā)電量的20%左右,而水輪機(jī)調(diào)速系統(tǒng)作為水輪發(fā)電機(jī)組重要的控制系統(tǒng)之一,具有非最小相位、非線性和時(shí)變性等特點(diǎn)。針對(duì)水輪機(jī)調(diào)速系統(tǒng)的特性,本文開展了小型水輪機(jī)調(diào)速系統(tǒng)綜合實(shí)驗(yàn)平臺(tái)研究與開發(fā)。該小型水輪機(jī)調(diào)速系統(tǒng)綜合實(shí)驗(yàn)平臺(tái)不僅可以研究水輪機(jī)調(diào)速系統(tǒng)在運(yùn)行過程中的特性以及可能出現(xiàn)的問題,而且可以為高等院校學(xué)生提供一個(gè)學(xué)習(xí)與研究水輪機(jī)調(diào)速系統(tǒng)的平臺(tái)。本文主要完成了以下工作:首先,本文提出了一種適用于小型水輪機(jī)調(diào)速系統(tǒng)的電液隨動(dòng)系統(tǒng)。該電液隨動(dòng)系統(tǒng)主要由液壓標(biāo)準(zhǔn)元件組成,采用電磁換向閥控制替代傳統(tǒng)的伺服閥或者比例閥控制,具有結(jié)構(gòu)簡(jiǎn)單、工作可靠、價(jià)格便宜、抗污染能力強(qiáng)等特點(diǎn)。其次,設(shè)計(jì)了一套小型水輪機(jī)調(diào)速系統(tǒng)綜合實(shí)驗(yàn)平臺(tái)的PLC控制系統(tǒng)。該P(yáng)LC控制系統(tǒng)采用德國(guó)西門子公司的SIMATIC S7-200系列PLC,具有功能強(qiáng)大,編程簡(jiǎn)單,可靠性高,通用性強(qiáng),擴(kuò)展靈活等特點(diǎn),對(duì)PLC控制系統(tǒng)的硬件設(shè)計(jì)和軟件設(shè)計(jì)進(jìn)行了詳細(xì)論述和實(shí)驗(yàn)驗(yàn)證。最后,詳細(xì)介紹了dSPACE實(shí)時(shí)仿真系統(tǒng)和綜合測(cè)量裝置,并以dSPACE實(shí)時(shí)仿真系統(tǒng)為基礎(chǔ)建立了水輪機(jī)發(fā)電機(jī)組模型,進(jìn)而搭建了小型水輪機(jī)調(diào)速系統(tǒng)綜合實(shí)驗(yàn)平臺(tái),并以小型水輪機(jī)調(diào)速系統(tǒng)為例對(duì)遠(yuǎn)程監(jiān)控系統(tǒng)的結(jié)構(gòu)組成及設(shè)計(jì)進(jìn)行了探討。
[Abstract]:At present, hydropower accounts for about 20% of the total power generation in China, and the speed governing system of the water turbine is one of the important control systems of the hydro-generator set, and has the characteristics of non-minimum phase, non-linearity and time-time degeneration. In view of the characteristics of the water turbine speed-regulating system, the research and development of the integrated experimental platform of the small-sized water turbine speed-regulating system are carried out. The integrated experimental platform of the small-sized water turbine speed regulation system can not only study the characteristics of the water turbine governing system in the running process and the possible problems, but also provide a platform for the students of higher learning to study and study the speed governing system of the water turbine. In this paper, a kind of electro-hydraulic follow-up system is put forward, which is suitable for small-sized water turbine speed-regulating system. The electro-hydraulic follow-up system is mainly composed of a hydraulic standard element, and is controlled by an electromagnetic directional valve to replace a conventional servo valve or a proportional valve, and has the characteristics of simple structure, reliable operation, low price, strong anti-pollution capability and the like. Secondly, a set of PLC control system for the integrated experimental platform of the small-sized water turbine governing system is designed. The PLC control system adopts the SIMATIC S7-200 series PLC of Siemens, which has the characteristics of powerful function, simple programming, high reliability, strong universality and flexible expansion. The hardware design and software design of the PLC control system are discussed in detail and verified. In the end, the dSPACE real-time simulation system and the integrated measuring device are introduced in detail, and the model of the turbine generator set is built on the basis of the dSPACE real-time simulation system. In this paper, the structure and design of the remote monitoring system are discussed with the small turbine speed regulation system as an example.
