In-core flux measurement is critical for monitoring and power regulation of a large core nuclear reactor. Self powered Neutron Detectors (SPNDs) are used for measuring the neutron flux in a nuclear reactor. In this paper we propose an online method for SPND gross error detection, identification and estimation. The method uses linear models which are extracted from data and which adapt continuously in time. This adaption is made possible by use of recursive PCA. However, unlike existing recursive PCA approaches which make approximations to achieve recursion, our proposed approach does not make any approximation. We term our technique as `Recursive Principal Component Analysis: Exact Computation' (RPCA-EC). Use of recursion ensures that the computational requirements of RPCA-EC are low thereby facilitating online implementation. Continuous adaption ensures that the model evolves to adequately capture the time varying relationships amongst the SPNDs. The relationships amongst the SPNDs vary with time due to significant variations in the neutron flux profiles in the reactor with varying operating power levels in the reactor. We apply our proposed method on data taken from an operating nuclear reactor in India and compare results with alternate implementations. Results show that the false alarm rate of our implementation is reasonable thereby indicating that the model adapts to time varying relationships. Performance in presence of gross errors is also satisfactory.

Due to fossil fuel depletion, power shortage has become a major problem in the world. This increases the importance of Distributed Energy Resources (DERs) among the consumers which in turn led to the expansion of microgrid. Microgrid operates in grid-connected mode as well as in islanded mode. Microgrid is connected to main grid in grid connected mode. In islanded mode, there is no such connection and hence the microgrid operates independently. Microgrid may move to islanded mode intentionally or unintentionally. power in the grid is not constant which in turn affected the loads connected to the grid. Due to the Sun light variation the voltage output from the grid may not be constant. In three phase microgrid, fault in one phase causes loss of voltage stability in other two phases. PID control has been used for microgrid voltage control but it does not work properly during fault conditions. So, an adaptive PI controller has been proposed to provide voltage regulation in microgrid which provides better performance under all the circumstances. The performance of the system employing adaptive PI controller is validated using the results obtained from the MATLAB Simulink.

A continuous and discrete time Linear Quadratic Regulator (LQR) based technique has been used in this paper for the design of optimal analog and discrete PID controllers respectively. The PID controller gains are selected as the optimal state-feedback gains corresponding to the standard quadratic cost function. Genetic Algorithm (GA) has been used next to optimally find out the weighting matrices, associated with the respective optimal state-feedback regulator designs while minimizing another integral performance index which comprises of a weighted sum of Integral of Time multiplied Squared Error (ITSE) and the controller effort. Next, the proposed methodology is applied with fractional order (FO) integral performance indices. The impact of these FO objective functions on the LQR tuned PID control loops is also highlighted, along with the achievable cost of control. © 2012 IEEE.

IEEE instrumentation and Measurement Technology Conference

The accurate measurement of oxygen content in flue gas at coal fired power plant is important for realizing closed-loop control and optimization of combustion processes. A cloud model is incorporated into the measurement of oxygen content in flue gas. A qualitative and quantitative transformation fusion model based on the cloud model theory is established. The oxygen content in flue gas from real-time measurement at coal fired power plant is estimated using traditional arithmetic average, weighted mean fusion method as well as cloud model theory. Practical tests were undertaken to determine the oxygen content in the flue gas by using the three methods for practical operating data. The test results show that the proposed method produces more accurate measurement values than the one given by the arithmetic mean of a finite number of sensors.

This paper proposes a new concept named Flexible, Reliable and Intelligent ENergy Delivery System (FRIENDS) as a future power distribution system. In FRIENDS, new facilities called Quality control Centers (QCCs), which consists of Voltage control type Inverters, Distributed Generators (DGs), Energy Storage systems (ESSs), etc., are installed between distribution substation and customers. By controlling and operating those inverters and DGs in QCCs adequately, balancing the supply and demand can be realized. Particularly, when the power supply from the transmission network is interrupted, isolated local network which consists of some QCCs are composed in order to realize uninterruptible power supply. In the isolated network, the DGs and ESSs in QCCs are employed as backup generators. This paper proposes a distributed and autonomous method for balancing the power system supply and demand during interruption period. This paper also investigates the effectiveness of the proposed method through computational simulations using MATLAB and LabVIEW. The results obtained using our hardware with MATLAB and LabVIEW were also compared with that of the one obtained using PSCAD. © 2011 IEEE.

Rational approximation of fractional order (FO) differ-integrators via Continued Fraction Expansion (CFE) is a well known technique. In this paper, the nominal structures of various generating functions are optimized using Genetic Algorithm (GA) to minimize the deviation in magnitude and phase response between the original FO element and the rationalized discrete time filter in Infinite Impulse Response (IIR) structure. The optimized filter based realizations show better approximation of the FO elements in comparison with the existing methods and is demonstrated by the frequency response of the IIR filters. © 2011 IEEE.

In this paper, the classical Least Square Estimator (LSE) and its improved version the Instrumental Variable (IV) estimator have been used for the identification of an ac servo motor position control system. The data for system identification has been collected from a practical test set-up for fixed command on the final angular position of the servo motor with varying level of velocity and acceleration. The measured data is corrupted then with externally induced random noise having a Gaussian distribution, commonly known as white Gaussian noise (wGn). Performance of the LSE and IV estimators are also compared for fractional Gaussian noise (fGn) which have heavy tails in its statistical distribution and are capable of modeling real world signals having spiky nature. © 2011 IEEE.

This paper analyzes a nuclear reactor power signal that suffers from network induced random delays in the shared data network while being fed-back to the Reactor Regulating System (RRS). A detailed study is carried out to investigate the self similarity of random delay dynamics due to the network traffic in shared medium. The fractionality or self-similarity in the network induced delay that corrupts the measured power signal coming from Self powered Neutron Detectors (SPND) is estimated and analyzed. As any fractional order randomness is intrinsically different from conventional Gaussian kind of randomness, these delay dynamics need to be handled efficiently, before reaching the controller within the RRS. An attempt has been made to minimize the effect of the randomness in the reactor power transient data with few classes of smoothing filters. The performance measure of the smoothers with fractional order noise consideration is also investigated into.
