【摘要】：根據(jù)液壓發(fā)電系統(tǒng)特性可知,其工作轉(zhuǎn)速由蓄能器壓力和發(fā)電機(jī)負(fù)載決定,而蓄能器壓力和發(fā)電機(jī)負(fù)載是實(shí)時(shí)變量,不加控制將無(wú)法實(shí)現(xiàn)液壓發(fā)電系統(tǒng)始終工作在最佳轉(zhuǎn)速曲線。特別是當(dāng)液壓發(fā)電系統(tǒng)整流后直接饋入海島直流微電網(wǎng)時(shí),轉(zhuǎn)速由直流電網(wǎng)電壓唯一確定。文中通過(guò)引入Boost變換電路,實(shí)現(xiàn)液壓發(fā)電系統(tǒng)轉(zhuǎn)速的實(shí)時(shí)控制。提出最高效率轉(zhuǎn)換控制策略,實(shí)現(xiàn)液壓發(fā)電系統(tǒng)始終工作在最佳轉(zhuǎn)速曲線。推導(dǎo)了液壓發(fā)電系統(tǒng)Boost變換機(jī)理,通過(guò)試驗(yàn)得到了最佳轉(zhuǎn)速曲線,建立了液壓發(fā)電系統(tǒng)經(jīng)過(guò)交錯(cuò)并聯(lián)Boost變換器饋入直流微電網(wǎng)的仿真模型。仿真結(jié)果表明,在Boost變換器控制下,液壓發(fā)電系統(tǒng)始終工作在給定的最佳轉(zhuǎn)速曲線,實(shí)現(xiàn)了液壓發(fā)電系統(tǒng)最高效率轉(zhuǎn)換控制策略。
[Abstract]:According to the characteristics of the hydraulic power system shows that the working speed by the pressure and the generator load decision accumulator, and the accumulator pressure generator and load is real-time variable, without control will not be able to achieve the hydraulic power system always work in the best speed curve. Especially when the hydraulic power system the rectified DC micro grid when fed directly to the island that speed is only determined by the DC voltage. In this paper, by introducing the Boost conversion circuit, real-time speed control of hydraulic power system is proposed. The highest conversion efficiency of hydraulic power control strategy, the system work at the optimum speed curve was deduced. Hydraulic power system Boost transformation mechanism, the optimum speed curve can be obtained by test, simulation model established by interleaved Boost converter fed DC micro hydraulic power system. The simulation results show that the Boost converter under the control of liquid The power generation system always works at the given optimal speed curve, and realizes the maximum efficiency conversion control strategy of the hydraulic power generation system.
