Plan power supply for static rectifiers
Static rectifiers are widely used for HVDC conversion and in industrial plants. Rectifiers disturb a power system by generating harmonic-frequency voltages and currents which affect power system equipment in many ways. The planning required so that a rectifier plant will have the least detrimental effect on a power system is discussed. Recommendations for total harmonic voltage are given. (LCL)
In support of the TCV experimental campaign aiming at studying H-mode plasmas with snowﬂake (SF) divertor, free boundary equilibrium and stability studies were performed with the SPIDER and KINX codes. Due to the high ﬂexibility of plasma shaping capabilities of TCV, SF divertor conditions can be reached for various plasma geometries. However, at high plasma current some conﬁgurations require poloidal ﬁeld (PF) coil currents close to the machine limit. This is particularly important when the equilibrium sensitivity to the edge pedestal proﬁles, which is higher than for standard X-point conﬁgurations, is taken into account. That is why the conﬁguration optimization should also include the proﬁle sensitivity study when planning the shot scenario.
