MSHS has experience and technical skills to retrofit Automatic Voltage Regulator (AVR) Excitation systems fitted on steam, gas, or hydro turbines or diesel or gas engines.
We retrofit simplex AVR systems to more complex redundant configuration excitation systems consisting of a brush or brushless rotating exciter, PMG or bus fed excitation systems, from field flashing to crow bar protection.
The MSHS engineering team retrofits individual AVR systems and AVRs as part of a larger engineered control system, featuring excitation system design, installation, and service for land or marine applications.
MSHS supports a range of Basler AVRs from DECS100 through DECS400 and ECS2100 Excitation Systems.
Environmentally rugged digital excitation control system is ideally suited for controlling the output of brushless excited synchronous generators up to 5MW. The DECS-100 is extremely affordable and perfect for machines that will be paralleled to other generators and/or to the utility system. It is ideal for distributed generation, co-generation and peak shaving applications.
One DECS-200 Digital Excitation Control System can accommodate 32Vdc, 63Vdc, or 125Vdc applications up to 15Adc. This unique flexibility provides precision control of virtually any size generators. The DECS-200 incorporates a pulse width modulated power stage, which improves system performances in non-linear load applications.
The DECS-200N is a very compact Negative Forcing Digital Excitation Control System. This multiple microprocessor-based design accommodates 63 Vdc and 125 Vdc applications up to 20 Adc continuously. The on-board six-thyristor controlled rectifier bridge offers the highest system performance possible, making the DECS-200N ideal for providing exceptional system response, which makes it suitable for applications requiring power system stabilizers.
Cabinet comprised of DECS400 AVR, Excitation (SCR), SCR Gate Firing module, Field Flashing Contactor, PPT. The DECS-400 is a microprocessor-based controller that provides excitation control, flexible logic control, and optional power system stabilization for synchronous machines in an integrated package. The controller provides an analog output to control the firing of external bridge(s) and monitors machine parameters to control, limit, and protect the synchronous machine from operating beyond its capability limitations.
The ECS2100 is a multi-microprocessor excitation control system that provides advanced technology to precisely control, protect, and monitor synchronous generators, including new and existing applications that are driven by all types of prime movers, such as steam, gas, hydro, and diesel. Its multifunctional design allows the ECS2100 to operate as a voltage regulator or as a static exciter, providing excitation currents up to 10,000 Adc.
