Department of Electrical Drive and Industrial Equipment University of Science and Technology (AGH) The article describes the method of determining mechanical losses and electromagnetic motor torque on the example of a flywheel energy storage system utilizing BLDC motor. The description of the test stand contains: the topology of power factor correction boost rectifier, an inverter supplying the BLDC...
The paper presents a method of investigation of grid connected systems with a renewable energy source. The method enables fast prototyping of control systems and power converters components by real-time simulation of the system. Components of the system such as energy source (PV array), converters, filters, sensors and control algorithms are modeled in FPGA IC. Testing the systems before its practical...
This paper presents the results of research of the rotating energy accumulator. In the study the brushless DC motor with permanent magnet (PN=2,98 kW) was used as the motor-generator. The rotating mass made up the steel pipe. This accumulator stored about 4 MJ kinetic energy. The rotation speed was 6000 rpm. The inverter was constructed from intelligent power modules. The control of this one is based...
