    ABSTRACT: This paper proposes solutions to the problem of voltage sags caused by distributed generators anti-islanding protection. This is a recently identified power-quality (PQ) concern resulting from the increasing penetration of distributed generators into distribution networks. This problem has been previously investigated by the authors and it was revealed that it can seriously affect PQ indices as well as distributed generators reconnection procedures. However, no solutions have been formerly proposed or investigated. In this context, this paper investigates several potential solutions to be adopted by the utility and/or by the DG owners and presents a thorough evaluation of their main advantages and disadvantages. Besides this investigation, simple step-by-step procedures for assessing the effectiveness of each solution are described. The presented studies and procedures will guide the utility engineers in decision-making process associated with the choice of reasonable mitigation techniques to this problem.

    ABSTRACT: This paper proposes a parallel multimodal optimization algorithm that is combined with electromagnetic transient simulation in a platform that unifies the setup, test, and execution of optimal designs for power systems. The algorithm speeds up the design of power systems as its computations can be executed independently on a highly parallelized environment. Additional speedup is achieved by using a surrogate model to estimate the objective function in regions of suspected local optima. The estimated functions can be used in the subsequent stages of postoptimization studies, such as sensitivity analyses. Comparative studies, in terms of computation time, are conducted against sequential execution of the proposed algorithm. The optimal design of a VSC-HVDC transmission is described to demonstrate the capabilities of the proposed algorithm.

    ABSTRACT: This paper highlights an immediate need for renewable generation developers, manufacturers, utilities and industry standardization institutes to jointly address a challenge of capacitor switching transient immunity in inverter-based wind or solar farms. The need was identified from wide-area operation records which showed partial or full generation loss in coincidence with routine utility-owned capacitor switching. The lack of a clear industry guideline has caused confusions to all involved parties. The paper recommends all entities to address this challenge collaboratively through enhanced equipment specification, design and test before a well-defined industry guideline becomes available.

    ABSTRACT: This paper proposes an implementation of distribution static compensator (DSTATCOM) for the three-phase distribution system. The functions of DSTATCOM are harmonics elimination, compensation of reactive power, and load balancing in power factor correction and voltage regulation modes. A variable forgetting factor recursive least square (VFFRLS)-based control algorithm is proposed for effective operation of DSTATCOM to estimate weighted values of active and reactive power components of load current. The proposed control algorithm is fast in convergence and has quick response. A prototype of DSTATCOM is developed in the laboratory using a digital signal processor (dSPACE 1104) and voltage-source converter and tested for various operating conditions under nonlinear load. The performance of DSTATCOM is found satisfactory in mitigating various power-quality problems with the VFFRLS-based control algorithm.

    ABSTRACT: A novel concept of hybrid dc vacuum circuit breakers (VCBs), based on the combination of zero-voltage switching (ZVS) and zero current switching principle, was developed to meet the needs of the dc zonal distribution system on shipboard rated for a current of several kiloamperes and a voltage of several kilovolts. In normal operation, the VCB handles the continuous flow of dc current, minimizing the onstate losses. When protection against the fault is requested, the current is first divided between the VCB and the static branch before being quickly interrupted under a forced commutation principle. Laboratory tests have been dedicated to characterize the reliability of the high-current commutation from the VCB to the static branch and the turnoff characteristic of the silicon-controlled rectifier under high-current conditions. Finally, the critical design of the high-speed VCB is discussed.

    ABSTRACT: This paper presents a general method for building equivalent electric circuits of power transformers, including eddy current effects in windings and core. A high-frequency equivalent dual model for single- and three-phase transformers with two multilayer windings is derived from the application of the principle of duality. The model is built from elements available in circuit simulation programs, such as Electromagnetic Transients Program (EMTP)–Alternative Transients Program, EMTP-RV, PSCAD, and PSpice. The parameters of the frequency-dependent leakage inductance and winding resistance are computed with analytical formulae obtained from the solution of Maxwell’s equations that are based on the geometrical dimensions and material information. Ideal transformers are utilized to isolate the electric components (winding resistors and capacitors) from the magnetic components (inductors). The physically correct connection points for electric and magnetic components are clearly identified. The proposed methodology is successfully validated versus finite- element simulations and laboratory measurements.

    ABSTRACT: A coupled computational fluid dynamics (CFD) and heat-transfer model for an ice-covered fiberglass-reinforced plastic (FRP) hot stick, elaborated in a previous study, could well explain why the flow of partial-discharge current could be sufficient to raise the temperature of an iced pollution layer just below freezing, where the cold-fog flashover mechanism prevails. However, the ice-covered hot stick was modeled as a solid “ice rod” having an equivalent cross section of ice, meaning that the exposed ice surface is smaller in the model compared to reality. In addition, the simulations were performed for a relatively low wind speed of 1 m/s, while average wind speeds of 6.1–14.4 m/s were reported for the two Manitoba flashovers. Both of these problems are addressed in this paper to deal with the site incident conditions. The ice cover is considered as a thin layer having a thickness of 1 mm on the FRP hot stick. The effects of wind speeds of 0.1–15 m/s and wind direction as parallel and perpendicular to the ice-covered FRP hot stick are studied. This paper also presents experimental investigations on the most reliable reproduction of four separate FRP hot stick flashover incidents in Canada achieved at CIGELE laboratories.

    ABSTRACT: Recently, a new oscillation phenomenon—intermittent subsynchronous oscillation (ISSO)—has been observed in a large interconnected power grid. Rather than leading to oscillatory instability, ISSO causes cumulative fatigue damage and reduces the shaft life of the generator. The existing phase-compensation-based damping technologies are found to be limited in mitigating these types of oscillations. To mitigate ISSO, a subsynchronous modulation of reactive current (SMRC) approach is established and implemented in the voltage-source converters (VSCs) at the generator terminals. The contribution of SMRC to system damping has been analyzed in order to select control parameters for the VSC. The SMRC controller has been prototyped and extensively tested on a real-time closed-loop simulation platform equipped with a newly developed speed sensor module for precisely interfacing the real-time digital simulator with the rotating speed-acquisition board. Extensive experiments on the input and output characteristics of the VSC have been carried out to test and validate the damping current generating module. The effective damping areas are obtained from test observations to fine tune the parameters of the VSC controller for adapting to various system operating conditions, resulting in the common optimal damping region. Real-time simulations, onsite commissioning, and statistics have demonstrated the ability of the SMRC to mitigate ISSO and subsynchronous oscillation in power plants.

    ABSTRACT: Frequency response measurement offers by far the most sensitive known technique to detect any mechanical deformation in transformer winding. By default, during this measurement, the neutral or line current is considered as the winding response. The overall sensitivity to detect a mechanical change depends not only on the response quantity and the terminal connections chosen, but, also on the arrangement of poles and zeros of the system function. Some pole-zero arrangements are inherently better suited to reveal mechanical changes. Because of this, it is imperative to examine whether neutral current is indeed the best response quantity to consider or there exists any other quantity, say e.g., total shunt current of the winding (also referred to as the tank-current), to accomplish this task better. With this motivation, this paper compares the resonance behavior of neutral and tank current. Based on analytical derivations and actual experiments, it emerges that for detecting simulated mechanical changes, the tank-current seems to be a more competent alternative compared to neutral current. It offers enhanced detection sensitivity, especially for interleaved windings. Possible reasons to explain why it so, are presented. Author believes that this finding needs reinforcement by field trials to ascertain its viability.

    ABSTRACT: Aeolian vibrations of transmission-line conductors may cause fretting fatigue failure at or near the location of clamped devices. At these locations, the bending stiffness variation of the conductor has a large influence on its deformed shape and, hence, on its fatigue mechanics. Variable bending stiffness models could be integrated in nonlinear finite-element programs to obtain better mechanical behavior predictions. However, there is very little data available in the literature to validate such numerical models. The objective of this paper is to present experimental data for the deformed shape of two types of ACSR conductors undergoing vibrations. The tests were performed on a 5.83-m test bench for various tensions, displacement amplitudes, and frequencies. The displacement amplitude was measured at the vibration anti-node and at five locations near the square-faced bushing. The results suggest a large stiffness variation near the bushing. This experimental study provides valuable data to compare with a numerical model of a vibrating conductor that includes variable bending stiffness.

    ABSTRACT: In Part II, we develop an efficient method for generating test cases that ensure early detection of design error. The proposed method uses the particle swarm optimization technique for the same. Also, we propose a sensitivity-based approach to rectify design errors. The proposed verification technique is applied on standard IEEE test systems and it is seen that it is possible to achieve better accuracy at significantly reduced computational complexity.

    ABSTRACT: Although transverse wind exerts an important influence on the distribution of the ion current density under HVDC transmission lines, very few experiments involving stable wind have been used to verify the numerical model. To overcome the variability of natural wind, a low-speed wind tunnel was used to produce stable wind in this research. An experimental platform was set-up in the wind tunnel, to measure the ion current density of DC wires. Based on the experiment, transverse wind exerted significant influence over the distribution of the ion current. The numerical model was discussed and the results showed reasonable agreement with the measured values for different wind speeds.
