Description: Lemcko was founded in 1998 as an independent academic research institute focusing on electrical motors, drives and electrical power quality to provide substantial research for its industrial partners. Since then, there has been a continuous growth in manpower, knowledge and expertise in low frequent power quality (2kHz) and electromagnetic compatibility and immunity (>9kHz). The laboratory has expanded its area of application, the test equipment and its expertise to cover these frequency ranges. The availability of a semi-anechoic chamber and the corresponding measuring equipment allows Lemcko to perform IEC and CISPR compliance testing.
It is, however, the lack of power as in voltage dips or short- or long-term blackouts that may affect the end user most noticeably. In 2012, Lemcko initiated research focusing on small-scale storage and autonomous generation of electrical power. Test facilities include a free-programmable power electronic converter (Tri-phase platform), 10kWp PV installation with tracking possibilities, net interactive PV converters in combination with battery storage and several autonomous generators. Future investments include a test facility for motor and generator testing of 150kW. This would allow for the possibility to test high power, high current as well as low speed generators such as the ones used in windmills 100kW.
Main Research Fields:
- Computational and simulation tools for power systems
- Transmission and distribution planning and operation
- Energy efficiency and power quality
- Energy interfacing with power electronic devices
- Renewable energy control and integration
- Optimal planning, control and operation of wind and PV farms
- Electricity markets
- Wave energy
- Wide-area control using PMUs
- Contribution of distributed generation to ancillary services
In Lemcko’s laboratory EELAB, a new testbench with 4-quadrant regenerative drive and gearbox has been installed. It reaches power scales of up to 150kW, speed ranges of up to 6000rpm and maximum torques of 45kNm. It is capable to:
- emulate wind turbines,
- work with co-generation applications and
- test the electrical specifications of rotating electrical machines.
