For multi - infeed hvdc systems , when the minimum eigenvalue of the system becomes zero , the voltage stability graph can be plotted effective short circuit ratio as function of coupling impedance 對于多饋入hvdc系統(tǒng),在最小特征值為零的情況下,可以根據(jù)這種關(guān)系作出有效短路比?連接阻抗圖,即電壓穩(wěn)定圖。
百科解釋
Short circuit ratio or SCR is the measure of the generator stability characteristics. It is the ratio of field current required to produce rated armature voltage at open circuit to the field current require for the rated armature current at short circuit.
