Description
Summary:The conceptual design of the capacitive energy storage intended for operation in laboratory conditions is considered. This capacitive energy storage includes the capacitor cells of 200 kJ stored energy, each incorporating one self-healing high-energy-density capacitor, one semiconducting switch unit on the basis of Light Triggered Thyristors (LTT) and the pulse diodes, as well as the toroid inductor. Power supply of the capacitive energy storage is provided by high voltage (HV) 3 × 10 kV, 50 Hz industrial electrical network, using the HV power transformer and phase-controlled rectifier. Special design for the capacitor cell and the module of capacitor cells is proposed, which provides easy access to all components of the capacitor cells during operation and maintenance. Control system of the capacitive energy system has a hierarchic structure and includes programmable logic controller (PLC), programmer for non-synchronous triggering of capacitor cells discharges and data acquisition system.
