In order to overcome the shortcomings of the present accuracy assessment methods of power system dynamic simulation, this paper focuses the permanent single phase short-circuit fault which occurs in a large probability in power grids,and selects the typical electrical quantities which is very concerned in engineering after the fault happened. A time-scale based error criteria on simulation validation is proposed, and a comprehensive error criteria according to the average errors between simulation data and actual data is proposed to evaluate objectively the simulation accuracy of the typical e

Abstract:

In this paper, the analytical formulations among the damping factor and the other parameters are studied by Melnikov method for the classic second-order model of power system. The proximity of Melnikov method is analyzed by comparison between the obtained critical damping factor with the result by time-domain simulation method. It points out that this method exist great error in the range of engineering application. To solve this problem, an improved method is proposed to calculate the critical damping factor based on RBFNN. Finally, simulations show that it can effectively improve the calcula

Abstract:

In the present power system stability analysis, BPA model for turbine and governor is commonly used. It simplifies the actual turbine system to a large extent, therefore the model simulation results may deviate from the actual conditions. In order to improve the actual data simulation accuracy, this paper compared the real and simulation data of power, high pressure cylinder (HPC) exhaust pressure and reheat pressure. Then calibrated and optimized the established model using the data of field operation. Meanwhile, the model modified method using actual data is given and guidance of parameters

Abstract:

Parallel simulation of fluid power systems using the transmission line modelling method offers the benefit of increased speed of execution, but requires the system model to be partitioned on to individual processors. Fluid power systems are characterized by a transport delay in the pipelines connecting physical components, which allows component models to be decoupled; this leads to simulations involving frequent interprocessor communication and low computational performance. This paper describes a method that enables faster simulations by reducing the communication bottleneck. By adjusting th

New types of power system transients with lower time constants are emerging due to the replacement of synchronous generation with converter interfaced generation and are challenging the modeling approaches conventionally applied in power system simulation.

There are also many other general simulation tools with libraries of elements suitable for power engineering.

Abstract:

Wind power has different characteristics compared to conventional energy sources. The main difference is that wind power fluctuates under the influence of meteorological variables. This gives rise to problems related to grid stability. It is therefore important to understand these variations and their predictability in order to improve the integration of wind power into grids. Wind power forecasts play an important role. In this study, the accuracy of Numerical Weather Prediction (NWP) wind speed forecasts over the period 1st Sept. 2013 – 31st Dec. 2016 has been investigated. This was done for

It is necessary for power laterally diffused MOSFETs (LDMOSFETs) to operate efficiently and reliably in high temperature (< 300 °C), hostile environments such as those found in downhole, space, automotive and aerospace applications. Currently, silicon-oninsulator (SOI) technology is a dominant method to achieve this goal due to low leakage current and complete electrical isolation. However, the buried oxide (BOX) layer causes self-heating, which can impact device performance, cause thermal runaway and shorten device lifetime. To address this issue, one solution is to combine a silicon thin fil

The hypothesis of this paper is that AI-based fault diagnosis can be further improved by taking into account all the available sensor inputs of the machine. In short, the more sensor inputs fed into the AI model, the more accurate and reliable the outcome of the fault diagnosis.

The number of alternatives which can be explored depends upon the number of simulations which can be fit into the time allotted for design.
