When the mod\u00adules are clev\u00ader\u00adly com\u00adbined and con\u00adnect\u00aded in series, a clean\u00adly shaped sinu\u00adsoidal volt\u00adage can be repro\u00adduced, which can be used to specif\u00adi\u00adcal\u00adly shift the cur\u00adrent phase rel\u00ada\u00adtive to the grid volt\u00adage. In this way, the STATCOM sys\u00adtem can gen\u00ader\u00adate or absorb reac\u00adtive pow\u00ader.

This allows the pow\u00ader elec\u00adtron\u00adics to be packed more dense\u00adly, which fur\u00adther reduces the space required by the sys\u00adtem. A sta\u00adble oper\u00adat\u00ading tem\u00adper\u00ada\u00adture also reduces the ther\u00admal load and thus extends the ser\u00advice life of the com\u00adpo\u00adnents.<\/p>\n<\/div>\n\n\n\n This is where the pow\u00ader dis\u00adtri\u00adb\u00adu\u00adtion and con\u00adtrol cab\u00adi\u00adnets for con\u00adtrol\u00adling, mon\u00adi\u00adtor\u00ading, and pow\u00ader\u00ading the STATCOM sys\u00adtem are locat\u00aded.
