As Photovoltaic (PV) penetration level rapidly increases in the modern power systems, the adoption of energy storage systems (ESS) is a preferred option to control the rapid and unpredictable PV power fluctuations. It is desired to develop new reliability evaluation methods that can model and evaluate the reliability impact of these new entries. This paper has proposed an area risk based method that...
With the development of wind power industry, early detection and diagnosis of incipient faults are desirable for the wind generators. A suitable model enables generator faults to be simulated and it is particularly useful for gaining an insight into their dynamic behavior and electro-mechanical interaction. In this paper a model of DFIG (Doubly-Fed Induction Generator) affected by stator inter-turn...
This paper introduces a modeling method of Three-stage Brushless Synchronous Machines. Three-stage Brushless Synchronous Machines' model is built by SimPowerSystems module and SIMULINK module in MATLAB. This model can be used to simulate both in electromotion-state and generating state. Compared with the common model, this model have the advantages of faster simulation speed and more intuitive.
A new approach based on the superposition fitting method is proposed for the parameters design and optimization of the transfer function for a novel doubly salient electrical generator (DSEG) with nonlinear inductance. The method to get the sorts of transfer function is adopted to build the simulation model to identification the uncertain parameters of DSEG using pulse-response results. Simulation...
Because of the difficulty of the direct measurements of the output voltage or current, a feasible approach is proposed to estimate the output parameters of the high-power pulse generator, which is based on the numerical calculation and the radiating measurement. The near-fields radiated from the biconical antenna are measured firstly, which is just excited by the pulser. Then the source functions...
