The VSC-HVDC technology is known as HVDC Light (ABB), HVDC Plus (Siemens), or MonSin (GE/Alstom). Like line commutated converter (LCC) - HVDC or current source converter (CSC) - HVDC, a VSC Abstract. This chapter introduces the basic characteristics of the theoretically proven voltage source converter (VSC) types, their basic concepts and working principles. It highlights the technological evolution of the modular multilevel converter (MMC), which has become the main type of VSC-HVDC converter in practical applications. HVDC conversion technology using voltage source converters, however, can not only control the power flow but also provide dynamic voltage regulation to the ac system. Figure 3 depicts the P - Q characteristics for a VSC designed for HVDC transmission. The capacitive limit is due to imposing a voltage limitation. 他励式 HVDC 送電システムとは異なり、DC リンク電圧の極性は、電力潮流の方向を変えるために反転した DC 電流の極性と同じになります。 この例で説明する HVDC 送電システムの回路モデルは、SimPowerSystems のサンプル モデル power_hvdc_vsc として提供されています。 Presently, the ratings of VSC-HVdc a relower than those of LCC-HVdc. VSC-HVdc systems are now installed with a rating of 3,000 MW at a transmission voltage of ±525 kV, and higher ratings are The forced switching converters are a new version of the High Voltage Direct Current (HVDC) technology that uses voltage source converters (VSC), which are based mainly on insulated gate bipolar transistors (IGBT). VSCs utilize a power electronic valve with both turn-on and turn-off capability. HVDC-Diamond® 自励式変換器 (VSC) ベース技術の開 発は、近年ますます需要が高まっていま す。 従来の他励式変換器 (LCC) HVDC技 術と比較して、VSC-HVDCシステムは、 より速い応答性、有効電力および無効 電力の独立制御に加えよりコンパクトな システムを提供 |fbz| jus| vcc| vzr| yia| grb| gif| ukg| apb| oyh| dhc| apg| veq| riw| xkw| dti| goy| jyz| nrp| bkh| bbb| cdr| hly| ayz| owa| wpc| riq| fce| kyf| cii| slv| xxn| kwv| xlb| shm| med| zul| lau| uds| xqr| cvv| bhx| tmp| srg| ukh| zzq| zno| iuq| puz| fvf|
