【摘要】：在介紹電力彈簧的研究背景和基本原理的基礎(chǔ)上,通過相量圖法對(duì)電力彈簧穩(wěn)態(tài)調(diào)節(jié)能力進(jìn)行詳細(xì)分析,得到電力彈簧穩(wěn)態(tài)運(yùn)行范圍,同時(shí)分析電力彈簧越限失靈的機(jī)理,給出了網(wǎng)側(cè)電壓越限條件下的關(guān)鍵負(fù)載電壓設(shè)定值優(yōu)化計(jì)算方法。若網(wǎng)側(cè)電壓在穩(wěn)態(tài)運(yùn)行范圍內(nèi)波動(dòng),經(jīng)電力彈簧調(diào)節(jié),可使關(guān)鍵負(fù)載電壓幅值穩(wěn)定到標(biāo)準(zhǔn)值;若超出穩(wěn)態(tài)運(yùn)行范圍,即發(fā)生越限,則受電力彈簧調(diào)節(jié)能力限制,關(guān)鍵負(fù)載電壓穩(wěn)定值會(huì)發(fā)生偏離,甚至?xí)l(fā)生電力彈簧失靈情況。通過優(yōu)化網(wǎng)側(cè)電壓越限情況下的關(guān)鍵負(fù)載電壓設(shè)定值計(jì)算方法,考慮關(guān)鍵負(fù)載電壓允許小范圍波動(dòng),可以保證電力彈簧在網(wǎng)側(cè)電壓越限情況下依舊正常工作,從而擴(kuò)大電力彈簧穩(wěn)定運(yùn)行范圍。最后,通過仿真實(shí)驗(yàn)對(duì)分析結(jié)果進(jìn)行了驗(yàn)證。
[Abstract]:On the basis of introducing the research background and basic principle of power spring, the steady-state regulating ability of power spring is analyzed in detail by phasor graph method, and the operating range of power spring steady-state is obtained, and the mechanism of power spring overstepping failure is analyzed at the same time. The optimal calculation method of the critical load voltage setting value under the condition of grid side voltage overstepping is given. If the grid side voltage fluctuates in the steady operation range, the amplitude of the critical load voltage can be stabilized to the standard value by the power spring adjustment. If it is beyond the range of steady operation, the limit will be exceeded, and the voltage stability of the critical load will deviate due to the limitation of the power spring's regulating ability. Even power spring failure will occur. By optimizing the calculation method of critical load voltage setting when the grid side voltage exceeds the limit, the critical load voltage can be allowed to fluctuate in a small range. It can ensure that the power spring can still work normally under the condition of the grid side voltage exceeding the limit, so as to expand the power spring's stable operation range. Finally, the analysis results are verified by simulation experiments.
