Basic design considerations for a mechanically switched capacitor with damping network (MSCDN) within a high-voltage-grid

Sensitivity analysis of the Electrical Stresses in Mechanically Switched Capacitors with Damping Network due to Components’ Tolerances

“…As already mentioned, a MSCDN consists of four components that are electrically connected as shown in The value of C 1 , C 2 , L are unequivocally defined by the required reactive power Q r , the nominal voltage U n at PCC, the selected tuning frequency f t and the nominal frequency of the power system f n . The mathematical relations are given in [1] and [2]. The tolerances of these three elements cause a detuning of the MSCDN.…”

Behavior of Mechanically Switched Capacitors with Damping Network (MSCDN) during Energization

“…The quality factor can be interpreted as the damping resistance normalized to rated voltage, reactive power and tuning frequency, as described in equation (4). It is especially useful when comparing MSCDN with different design criteria.…”

“…During the design phase of the MSCDN, both steady state voltage stress and losses and transients during switching of the MSCDN have to be considered. There have been many investigations with different scope conducted, using various methods for the design of the MSCDN ( [3], [4], [5], [6], [2]).…”
