This paper describes and compares the performance of Adaptive Neuro-Fuzzy, Takagi-Sugeno (TS) type Fuzzy Logic and the conventional Proportional Intergral (PI) controllers applied to three-phase Shunt Active Filter (ShAPF) for Power Quality improvement and reactive power compensation required by non-linear loads. The Simulation results show that the Adaptive Neuro-Fuzzy Inference System (ANFIS) proves to be better than the Fuzzy and PI controllers as it combines the best features of Neural Networks and Fuzzy Systems.
Energy has been universally recognized as one of the most important inputs for economic growth and human development but due to increasing pressure of population and increasing use of energy in different sectors of the economy is an area of concern for India. According to 2011 energy survey, there is a huge gap between energy demand and energy production in India. Since the industrial revolution, fossil fuel has become the primary source of energy to produce electricity but the use of fossil fuel is not eco friendly as it produces greenhouse effect. Besides the environmental effects, all the reserves of primary sources of energy are on their way to getting used up. Among the total electricity produced per year, 35 to 40 percent of primary energy is consumed by the household sectors. So the reduction of energy consumption in buildings is of high socio-economic relevance. Besides the reduction of energy consumption we have solar energy which is far better than fossil fuel and it is the most abundant energy available in the planet. Due to enormous advantages of solar energy, an innovative design of sustainable building is presented in this paper where solar energy is used to make it a zero energy building. Green building also indirectly helps to reduce green house gas emission and pollution produced by the combustion of fossil fuels. In this paper also the electricity supply control, lighting control and solar tracking control are designed using programmable logic controller (PLC) which helps to increase the power supply security and the overall efficiency of the building. The automation system has been designed and tested using GE, FANUC PLC.
In this paper, a new hybrid active power filter using a voltage-source power converter with a series connected inductor and capacitor set is proposed. The power converter is controlled to produce a voltage proportional to the harmonic component of the load current. The compensating current flows into the power feeder via the series connected inductor and capacitor set and suppresses the harmonic currents generated by the nonlinear loads. The advantages of the proposed filter are low voltage rating of dc capacitor and power switches, smaller inductor, and low Electro Magnetic Interference.
Several authors have published work related to detection of fault in high voltage transformers using Sweep Frequency Response Analysis (SFRA), Wavelet and Coherence. The work published in this paper describes the result of analysis of neutral current during reduced and full impulse voltage test of 400 KV transformers with detailed analysis using Coherence Function (CF). It is aimed at determining the variation of CF due to change in neutral current for transformers which have either passed or failed during certification test. In order to establish criteria, theoretical simulation was carried out initially to determine the nature of CF for different types of noise superimposed on impulse wave. The analysis was done for high voltage transformer by recording neutral current during calibration and full impulse voltage test of high voltage winding, using data obtained during testing. Of the three types of transformers, two have passed the test and one has encountered major failure. For the purpose of analysis the two outputs i.e. neutral currents at reduced and full voltage with appropriate scaling were used. The assumption is made that for similar inputs, outputs must remain similar as long as the equivalent electric circuit remains unchanged. In the event of any change by way of fault, electromagnetic interference and jitter, the CF is likely to be less than unity.
The paper deals with the comparison of the performance and dynamic characteristics of a three-phase three-wired active power filter using Sliding Mode Control (SMC) and Synchronous Reference Frame (SRF) control strategy for power quality improvement. Sliding mode control implements discontinuous feedback control laws to strengthen the system state to reach, and consequently to remain on, a specified surface within the state space called as sliding surface In SRF control strategy for three-phase systems, reference frame transformation from stationary a-b-c frame to synchronous rotating d-q reference frame can change ac quantities in synchronous frequency into dc quantities which can be controlled by a PI controller. The objective is to enhance phase current waveform, THD reduction and reactive power compensation in electric power distribution system. Shunt Active Filter can efficiently introduce the current into the distribution by the power electronics based control. Thus MATLAB simulated results demonstrate that Shunt Active Filter can be considered as a viable solution for THD Reduction of supply current and reactive power compensation.
This paper describes the development of BLDC motor characteristics using a digital signal processor (DSP) motion control kit (MCK28335 kit). This technique provides a highly accurate and robust sensorless operation from near zero to high speeds. The dynamic characteristics like speed and as well as currents can be efficiently monitored and analyzed by using this Kit. The block commutation control method is used to drive the motor included in the MCK28335 kit using a TMS320F28335 motion application.
