In order to analyze the impacts on the grid fault identification criteria in stability control systems (SCSs), an electromagnetic transient model is set up for a three-machine nine-bus test system containing wind power generators. Then, an analysis of impacts on adjacent AC grid fault characteristics of wind power integration and its power electronics based control systems and a discussion of problems...
This paper uses the grid-connected photovoltaic (PV) power plant electromechanical transient simulation model on FASTEST (Fast Analysis of Stability using the Extended equal area criterion and Simulation Technologies) to do the simulation of PV power plant integrated to the grid. The simulation includes the largest installed capacity of PV power plant and the response of PV power plant when solar...
The local binary patterns statistical characteristics of the continuous wavelet transform scalogram of the aeroengine vibration signal are explored in this paper. The method is based on recognizing that certain uniform local binary patterns which are fundamental properties of local image texture and their occurrence histogram is proven to be a very powerful texture feature. Three patterns are studied...
Jet engine gas path fault diagnosis is not only important in modern condition-based maintenance of aircraft engines, but also a challenging classification problem. Exploring more advanced classification techniques for achieving improved classification performance for gas path fault diagnosis, therefore, has been increasingly active in recent years in PHM community. To that end, in this paper, we apply...
Locomotives are complex electromechanical systems. Continuously monitoring the health state of locomotives is critical in modern cost-effective maintenance strategy. A typical locomotive is equipped with the capability to generate fault messages or incidents based on logical rules in the control system. In the mean time, sensor readings and operational state variables are also collected. The goal...
