Insulators plays a major role in power transmission system, which provides mechanical support to conductors and are used to decrease the leakage current flowing from conductor to earth. In this paper, the author attempts to design and study of voltage distribution and electric field distribution of various types of disc insulators when they are stressed by high voltages. In this paper, OPERA electromagnetic field analysis software is used to setup a two-dimensional model and FEM is employed to simulate 132 KV insulator strings with various types of porcelain, glass and composite disc insulators. The OPERA-2d/ST and Lossy Dielectric programs are used to return the field parameters, including the electric field intensity distribution as well as the distribution of the potential on the surface of insulator. The results obtained for various insulators were compared.

In recent years generation of electricity using wind power has received considerable attention worldwide. Induction machines are mostly used as generators in wind power based generations. Since induction machines have a stability problem as they draw very large reactive currents during fault condition, reactive power compensation can be provided to improve stability. This paper deals with the Impact of STATCOM on the Wind Farm performance. The essential feature of the STATCOM is that it has the ability to absorb or inject fastly the reactive power with power grid entirely by means of electronic processing of the voltage and current waveforms in a voltage source converter (VSC). This function is identical to the synchronous condenser with rotating mass. In the present work transient stability improvement and critical clearing time(CCT) analysis using STATCOM under faults is proposed. Improvement of transient stability with and without STATCOM and reactive power injection by STATCOM is studied. Simulation results are given, commented and discussed. The test results prove the effectiveness of the proposed STATCOM controller in terms of fast damping the power system oscillations and restoring the power system stability.
近年来,利用风力发电在世界范围内受到了相当大的关注。感应电机主要用作风力发电的发电机。由于感应电机在故障状态下产生的无功电流非常大,存在稳定性问题,因此可以通过无功补偿来提高其稳定性。本文研究了STATCOM对风电场性能的影响。STATCOM的本质特点是通过对电压源变换器(VSC)中的电压和电流波形进行电子处理,将无功功率完全吸收或快速注入电网。这一功能与旋转质量的同步冷凝器相同。在目前的工作中,提出了在故障情况下利用STATCOM进行暂态稳定改善和临界清除时间分析的方法。研究了有STATCOM和无STATCOM对系统暂态稳定性的改善以及STATCOM对系统无功功率的注入。给出了仿真结果,并对其进行了评论和讨论。实验结果证明了该控制器在快速抑制电力系统振荡、恢复电力系统稳定方面的有效性。

Multilevel inverters have gained lot of prominence in recent times due to their improved output quality at reduced switching stress. At high power levels a two level inverter have high switching stress as the entire supply voltage appears across the switch but in multilevel it is distributed among the switches. The most popular topology among multilevel inverters is DCMLI. But DCMLI suffers from neutral point voltage balancing problem this has raised due to unequal charging and discharging of capacitors. Many CB PWM solutions have been proposed for this problem in all this cases the underlining principle was adding a relevant dc bias to reference signal. In this paper a new technique is proposed. In which dc bias of the carrier is adjusted as per the polarity of capacitor voltage difference and neutral current. The proposed concept is tested using MATLAB simulation software.
近年来,多电平逆变器由于其在降低开关应力下提高了输出质量而得到了广泛的关注。在高功率水平下,双电平逆变器具有高开关应力,因为整个电源电压出现在开关上,但在多电平逆变器中,它分布在开关之间。在多电平逆变器中最流行的拓扑是DCMLI。但由于电容充放电不均匀,DCMLI存在中性点电压平衡问题。针对这个问题已经提出了许多CB PWM解决方案,在所有这些情况下,强调的原则是在参考信号中添加相关的直流偏置。本文提出了一种新的技术。其中载流子的直流偏置根据电容器电压差和中性电流的极性进行调整。利用MATLAB仿真软件对所提出的概念进行了验证。

This paper explains Z source inverter (ZSI) having unique impedance network with its operation, control and simulation. Traditional current source and voltage source inverter (VSI and CSI) have various conceptual and theoretical barriers with some limitations. All these are overcome by ZSI. It provides a novel power conversion concept. Z source concept can be applied to all ac-ac, dc-dc, ac-dc, dc-ac power conversion. In ZSI, modified PWM signal is used, which accommodates shoot through (ST) signal in order to buck or boost the DC input voltage, from a value between zero and infinity. To facilitate understanding of Z source inverter modulation, this paper work presents a detailed analysis, showing how Z source inverter is more advantageous than traditional current and voltage source inverter.

Increased electric power demand in a deregulated power system causes transmission lines to be driven beyond their transfer limits and causes violation of their limits which results to over load of lines. Available Transfer Capability (ATC) of a transmission system is a measure of unutilized capability of a system at a given time. The computation of ATC is very important to operate the transmission system more secure and the paper focuses on increasing the power transfer capability using FACTS devices like TCSC (Thyristor Controlled Series Capacitor), TCPAR (Thyristor Controlled Phase Angle Regulator), SVC (Static Var Compensator). These FACTS devices are optimally placed on transmission system using Sensitivity approach method. The proposed method is to enhance the ATC on Modified IEEE-14 bus system Using Power World Simulator 17software.

This paper focuses on an Artificial Neural Network (ANN) controller based Shunt Hybrid Active Power Filter (SHAPF) for compensating the harmonics of the distribution system. To enhance the performance of the conventional controller (Hysteresis controller) and to take advantage of intelligent controllers, a back propagation algorithm based feed forward-type ANN technique is implemented in shunt active power filter for producing the controlled pulses required for IGBT inverter. The proposed approach mainly work on the principle of energy stored by capacitor to maintain the DC link voltage of a shunt connected filter and thus reduces the transient response time when there is abrupt variation in the load. The complete power system set model of the proposed filter technique has been developed in MATLAB. The control algorithm developed is very simple. Simulations are carried out for the proposed scheme by using MATLAB, it is noticed that the %THD is reduced to 2.27% from 29.71% by ANN controlled filter. The simulated experimental results also show that the novel control method is not only easy to be computed and implemented, but also very successful in reducing harmonics.
研究了一种基于人工神经网络(ANN)控制器的并联混合有源电力滤波器(SHAPF),用于配电网谐波补偿。为了提高传统控制器(滞环控制器)的性能,并充分利用智能控制器的优势,在并联有源滤波器中引入了一种基于反向传播算法的前馈型人工神经网络技术,以产生IGBT逆变器所需的控制脉冲。该方法主要利用电容储能的原理维持并联滤波器直流链路电压,从而减少负载突变时的瞬态响应时间。在MATLAB中建立了该滤波技术的完整电力系统集模型。所开发的控制算法非常简单。利用MATLAB对该方案进行了仿真,结果表明,采用人工神经网络控制滤波器后,系统的THD %由29.71%降低到2.27%。仿真实验结果表明,该控制方法不仅易于计算和实现,而且在降低谐波方面取得了很好的效果。

The power swing caused by various transient disturbances which exists only for a few seconds will affect the zone 3 distance relay behavior and may result in relay mal-operation. By improving the operation of zone 3 distance relays, it is possible to prevent mal-operations, so that the cascaded line tripping is avoided. This paper proposes a transient stability prediction based on polynomial curve fitting method. The novelty of the proposed method is that it accurately predicts the transient stability based on only few samples of fault data with solving computationally extensive electromechanical dynamics and also determine the optimal tripping time for zone 3 so that the relay will be block the tripping for stable power swings. Performance of the proposed scheme is evaluated on the IEEE 14 bus system and the results are presented in this paper.
各种瞬态扰动引起的功率摆动仅存在几秒钟,就会影响3区距离继电器的行为,并可能导致继电器误动作。通过改进3区距离继电器的操作,可以防止误操作,从而避免串级跳闸。提出了一种基于多项式曲线拟合的暂态稳定预测方法。该方法的新颖之处在于,通过求解计算量较大的机电动力学问题,仅基于少量故障数据样本就能准确地预测暂态稳定性,并确定3区最优脱扣时间,使继电器在稳定的功率波动时能够阻止脱扣。本文在IEEE 14总线系统上对该方案进行了性能评估,并给出了测试结果。
