Transient performance analysis of low voltage connected microgeneration

A. S. Emhemed; R. M. Tumilty; G. M. Burt; J. R. McDonald 2008 IEEE Power and Energy Society General Meeting - Conversion and Delivery of Electrical Energy in the 21st Century, 2008

The growing awareness of the environmental impacts of large-scale thermal generating units has stimulated interest in microgeneration that is installed within domestic or commercial premises. This paper investigates the transient response to be expected from a range of microgeneration units that could typically be connected. The paper examines the impact of fault locations, typical fault clearance times and generator/prime mover ...

On-Line Sensor Diagnosis of the Diesel Engine Cold Starting Based on RBFNN

Mingjiang Hu; Zhong Wang; Yinnan Yuan; Liqiao Qi 2009 IEEE Circuits and Systems International Conference on Testing and Diagnosis, 2009

Based on the radial basal function neural network (RBFNN) and the OLS arithmetic, an on-line sensor fault detection diagnostic strategy on the diesel engine cold starting is proposed. This diagnostic strategy is conducted by RBFNN .The data of sensor sampling is the input and the sensor faults is the output of RBFNN. Some samples could be trained and studied by ...

Simulation investigations of ship power systems

Ryszard Arendt 2011 10th International Conference on Environment and Electrical Engineering, 2011

Basic structures and component elements of ship propeller and electrical power subsystems are presented. Chosen mathematical models of system component elements are discussed. Simulations of ship power subsystem, consisting of Diesel engine, gear, controllable pitch propeller and shaft generator are carried out.

Tests for positive jumps in the intensity of a Poisson process: a power study

M. Engelhardt; J. M. Guffey; F. T. Wright IEEE Transactions on Reliability, 1990

Tests are considered for the hypothesis of a constant intensity against the alternative of an intensity which increases with time in a nonhomogeneous Poisson process. Attention is focused on step-function alternatives and tests designed for such alternatives. One application is testing for abrupt changes in equipment following scheduled overhauls. The authors recommend the order- restricted likelihood-ratio test over an ordered ...

Kalman filtering for real-time individual cylinder air fuel ratio observer on a diesel engine test bench

J. Chauvin; P. Moulin; G. Corde; N. Petit; P. Rouchon 2006 American Control Conference, 2006

We propose an estimator of the individual cylinder air fuel ratios in a turbocharged diesel engine using as only sensor the single air fuel ratio sensor placed downstream the turbine. The observer consists of a time-varying Kalman Filter based on a physics-based model for the engine dynamics. We prove that the reference system converges toward a limit cycle. This limit ...
