【摘要】：模塊化多電平換流器(MMC)已成為柔性直流輸電系統(tǒng)的主流拓撲結(jié)構(gòu),其主設(shè)備參數(shù)的設(shè)計對系統(tǒng)的投資和運行性能具有決定性作用�；谀K化多電平換流器的高壓直流輸電(MMCHVDC)系統(tǒng)關(guān)鍵主設(shè)備參數(shù)包括聯(lián)接變壓器二次側(cè)額定電壓、變壓器漏抗、橋臂電抗、子模塊電容等,單個主設(shè)備參數(shù)的獨立設(shè)計忽略了不同設(shè)備多個參數(shù)之間的耦合特性。文中構(gòu)建了不同設(shè)備多個參數(shù)設(shè)計的約束方程組和目標函數(shù),并提出了基于非線性規(guī)劃法對MMC-HVDC系統(tǒng)主設(shè)備參數(shù)設(shè)計的整體算法,該整體算法綜合考慮多個參數(shù)和不同設(shè)備設(shè)計原則之間的耦合特性,從而達到可靠的優(yōu)化設(shè)計結(jié)果。最后針對某MMC-HVDC系統(tǒng)工程進行了參數(shù)優(yōu)化設(shè)計,基于PSCAD/EMTDC的計算和仿真結(jié)果基本吻合,驗證了所提算法的有效性。
[Abstract]:Modularized multilevel converter (MMC) has become the mainstream topology of the flexible DC transmission system. The design of the main equipment parameters plays a decisive role in the investment and operation performance of the system. The key main equipment parameters of HVDC system based on modularized multilevel converter include secondary rated voltage of connecting transformer, leakage reactance of transformer, reactance of bridge arm, capacitance of submodule, etc. The independent design of single main device parameters ignores the coupling characteristics between multiple parameters of different devices. In this paper, the constraint equations and objective functions for the design of multiple parameters of different equipments are constructed, and a global algorithm for the design of main equipment parameters of MMC-HVDC system based on nonlinear programming method is proposed. The whole algorithm takes into account the coupling characteristics of multiple parameters and different design principles of equipment, so as to achieve reliable optimal design results. Finally, the parameter optimization design of a MMC-HVDC system is carried out. The calculation results based on PSCAD / EMTDC are in good agreement with the simulation results, which verify the effectiveness of the proposed algorithm.
