   A Robust Model Reference Adaptive Control Applied For Power Quality Conditioning Devices
By Joao Marcos KANIESKI, Hilton Abilio GRUNDLING [View]
[Download]

Abstract: This paper proposes a hybrid control algorithm for a power quality conditioning device. This algorithmincorporates a Linear Quadratic Regulator (LQR) to a Robust Model Reference Adaptive Controller(RMRAC) in order to obtain a high performance and robust system of control for the specified plant.The RMRAC controller is developed to deal with parametric variation and system uncertainties, whilethe LQR scheme is designed to deal with disturbances caused by high line impedance. Thus, the hybridcontrol structure guarantees a good tracking performance for the plant to be controlled, considering ahuge class of uncertainties, commonly found in real systems. The power conditioning topology consistsof a Shunt Active Power Filter (SAPF), that uses a three-phase three-legs Voltage Source Inverter (VSI),connected to an L filter.

Abstract: In thermoelectric power plants the electrostatic precipitators are used to dedusting of high gas flow resulted the coal’s burning.For a plate-type electrostatic precipitator area was made an analysis upon charging of dust particles and a numerical modeling on electric potential and electric field strength for real field duct from ESP, with pulse energization. The numerical analysis was made without clean gas and with dusty gas dust operation of electrostatic precipitator.The analysis was made by finite element method for transversal cross-section of a duct from electrostatic precipitator field, when it is supply with pulse energization.

   Powering Low Cost Utility Sensors Using Energy Harvesting
By Rohit MOGHE, Frank LAMBERT, Deepak DIVAN [View]

Abstract: This paper presents the use of magnetic-field and solar energy harvesting to power low-cost utilitysensors. As we move towards a more dynamic and intelligent electricity grid, inexpensive smartsensors that help in extracting information on current, temperature and voltage from different utilityassets are becoming vital for maintaining high reliability of the power grid. Maintenance free sensorsthat do not require batteries for operation can be developed with the use of efficient energy harvestingtechniques. This paper presents a novel 0.2 V to 3.3 V AC-DC boost converter which convertsmagnetic field (H-field) and solar energy to electrical energy used by the sensor electronics. Asupercapacitor has been used to operate the sensor even in an outage. Numerous design constraintshave been identified. Further, a low-cost power circuit has been fabricated and experimentally testedto show functionality under varying operating conditions. Finally, analysis under faulted conditionshas also been presented to show the robustness of the power circuit.
