The ITER Electrical Power Supply Systems comprise the Electrical Power Distribution (EPD), the Coil Power Supplies (CPS) and the Heating and Current Drive Power Supply Systems (H&CD PS). They will be connected to the French 400 kV power transmission grid, which will supply about 120 MW steady-state power required by the standard auxiliary loads and 500 MW, 200 Mvar pulsed power for the plasma...
Each ITER Heating Neutral Beam injector (HNB) is designed to deliver up to 16.5 MW of additional heating power to the plasma, by accelerating Deuterium or Hydrogen negative ions down to -1MV with a beam current as high as 40 A in D- or 46 A in H-, for as long as 3600 s.
The performance required to this HNB, in terms of energy, power and beam-on time, goes far beyond the limits that have been...
One of the main objectives of JT-60SA, the satellite tokamak under construction in Naka (Japan), is to confine steady-state high-beta plasmas. To reach the desired plasma performance, the control of the instabilities called Resistive Wall Modes (RWMs) is crucial. At this purpose, besides the combination of an in-vessel passive structure (stabilizing plate) and plasma rotation, a dedicated...
Southwestern Institute of Physics (SWIP) is establishing a new tokamak (HL-2M) which needs about doubled power capacity and energy than its existing tokamak (HL-2A). The HL-2M power supply system shall meet these requirements, make full use of existing power supply equipment and provide the operation compatibility for both HL-2A and HL-2M.
Besides three existing flywheel six-phase motor...
This paper presents new technique using fuzzy logic controller to improve the performance of the ITER poloidal field (PF) converter systems. A fuzzy controller is considered for ITER PF converter system, using the conventional PI controller and Fuzzy controller (FC). The dynamic behavior and transient response of the PF converter system in circulating mode is proposed under normal operation by...
