MAEX: Modular Analog Excitation System Dynamic Excitation for Emergency Diesel Generators (EDG)
MAEX is a software-free modular excitation system for brushless generators. It has a highly ﬂexible design, which can easily be applied to existing infrastructures. The base module fulﬁlls all safety relevant functions for voltage regulation and signaling. An optional extension module provides manual control (additional redundancy), monitoring features as well as cos ϕ and reactive load control. Standard add-ons such as converters for diﬀerent voltage supply allows ﬂexible designs to consider special customer requests. A standardized power supply interface facilitates diﬀerent power supplies by a Permanent Magnet Generator (PMG), shunt supply by potential transformers (PT) or diﬀerent auxiliary supply from an alternating uninterrupted power supply (UPS). Accelerated start-up of generator voltage is accomplished by Field Flashing.
