Grid interface challenges and candidate solutions for the Compact Linear Collider's (CLIC) klystron modulators

This paper discusses the grid interface challenges for CERN's proposed Compact Linear Colliders' (CLIC) klystron modulators, including a 280 MW power system optimisation. The modular multilevel converter is evaluated as a candidate topology for a Medium Voltage grid interface along with a control method for reducing the impact of klystron modulators on the electrical network.

“…The candidate solutions for the power system grid interface, including both converter topologies and distribution equipment, are presented in [6]. Considering all potential structures presented in [6], and the required functionalities to be achieved, the optimal solution will be selected. Dedicated optimal grid layout is defined by the power system design approach, distribution voltage levels and quantity and ratings of the transformers, and converters, etc.…”

The Compact Linear Collider (CLIC) is an electron-positron collider under study at CERN with the aim to explore the next generation of high precision/high energy particles physics. The CLIC's drive beams will be accelerated by approximately 1300 klystrons, requiring highly efficient and controllable solid state capacitor discharge modulators. Capacitor charger specifications include the requirement to mask the pulsed effect of the load from the utility grid, ensure maximum power quality, control the derived DC voltage precisely (to maximize accuracy for the modulators being implemented), and achieve high efficiency and operability of the overall power system. This paper presents the work carried out on the power system interface for the CLIC facility. In particular it discusses the challenges on the utility interface and analysis of the grid interface converters with regards to required functionality, efficiency, and control methodologies.
