This article develops three different hydro turbine and governor (HTG) models to fulfill adequate modeling requirements for the representation of hydro power generation in the Nordic grid. To validate the performance of the developed models, both off-line and real-time simulation studies on a singlemachine infinite-bus (SMIB) system are carried out. Apart from SMIB system, real-time simulations are...
This paper presents a real-time simulation model for photovoltaic (PV) generators and a novel power conditioner for connecting solar energies into the electric grid. The power conditioner is composed of a zigzag-connected chopper (ZCC) converter and a series active power filter, which is controlled by PWM signals with a very high frequency of 20 kHz. A new set of converter models with interpolation...
In this paper, power system electromagnetic and electromechanical transient hybrid real-time simulation technology is expounded in details, which has advantages of the electromagnetic transient simulation program and electromechanical one. The more details needed to analyze the dynamic characteristics of power systems are provided by this hybrid simulation technology, and the scale of power system...
Along with the rapidly advancement of the computer hardware and software technology, special-purpose simulation computer system has gradually failed to keep pace with the developing and application trend of simulation technology. So in its development process, simulation computer gradually got rid of the customization road, gradually choose a common path. KDRTS (Ke Da real time simulation system),...
In the background of current realization of the hardware-in-the-loop (HITL) simulation system for guided weapon, this paper develops and expands the function module of battleplane simulator and proposes specific framework of the portable general battleplane simulator. Based on the strengthening industrial personal computer hardware, it carries out general battleplane simulator for portable guided...
Designing an all-electric ship (AES) requires testing of the interaction between hundreds of interconnected power electronic subsystems built by different manufacturers. Such integration tests require large analog test benches or the use of actual equipment during system commissioning. Fully digital simulators can also be used to perform Hardware-in-the-Loop (HIL) integration tests to evaluate the...
In this paper, we propose the expected schedulability to characterize the schedulability for the stochastic tasks on a single real-time computer processor. Our results show that the stochastic model has more flexibility to characterize the real-time tasks than the deterministic model. The expected schedulability is related to the real-time t at tasks arrival and may show that a sub-set of task would...
We present an improved texture synthesis algorithm over arbitrary surfaces in this paper. The algorithm adopt the searching strategy of restriction degree to compute the texture coordinates of each triangular patch. It reduces the restrictive conditions as searching for the best matching patches and debases the complexity of the algorithm at the same time. Then aiming at the local boundary unmatching...
