Electromagnetic transient processes in a network with a conventionally twelve-phase thyristor compensator designed to adjust the value of the starting transient current of the network in the case of direct start from the network of asynchronous motors of comparable power to the network with a jump-like change in the control angle of the thyristors in the bridges were studied. A comparison was made with such a change in the control angle of thyristors of transient currents in the circuits of a two-bridge controlled thyristor compensator with parallel connection of bridges with transient current

In this paper was presented the technical procedure implemented for the fault diagnostics of the thyristor bridge in an АС/DC converter. During the development of the new generation of digital controllers for AC/DC converters, it was required for these devices to have a possibility for a real-time detection of the thyristor converter fault. Thyristor bridge fault should be detected without the need for the state monitoring of the particular power semiconductor switches or rapid fuses. Thyristor bridge fault was identified using the measurement of the line-frequency second harmonic in the recti

The main mode of operation of synchronous machines in electric drives of industrial plants is the mode in which a static load moment close to the nominal is applied to the shaft. If the synchronous machine works as a generator, when consumers of comparable power are connected to the stator to stabilize the output voltage of the generator, forcing of the excitation voltage is applied by influencing the control angles of the thyristors of the controlled rectifier.

Purpose: Two possible variants of power sources are considered: controlled three-phase bridge rectifier circuit with a step-down transformer and a pulse converter, getting power from the mains via uncontrolled three-phase bridge rectifier (Larionov circuit) for bringing into rotation with the required frequency of wheel-motor units of electric locomotives and electric trains at the position of indiscriminate diagnosis of bearings. In both cases, it is assumed that power sources receive electro-energy from a depot circuit — 380/220 V, 50 Hz. The comparison of proposed power supply options based

Abstract With the widespread use of underground cables, a large amount of distributed capacitance is added to the urban power grid circuit, which brings great challenges to the transmission capacity and stability of the system. The mainstream suppression control method of distributed capacitance of power grid cable mostly depends on the characteristics of power grid cable material itself. In practical engineering applications, the characteristics of cable material itself are easily affected by environmental factors, which affects the suppression and compensation effect. In view of the above pr

This current depends on completely different parameters probably the voltage magnitude, the switching on angle the permanent flux, the core physical phemeon characteristics, the primary circuit resistance, etc. To beat the issues arising owing to transients, these are required to be suppressed.In this paper, an easy and economical techniquie is conferred to limit the transient current of the Y-yg transformers.

In order to realize the unsupervised extraction and identification of fault features in power electronic circuits, we proposed a fault diagnosis method based on sparse autoencoder (SAE) and broad learning system (BLS). Firstly, the feature is extracted by the sparse autoencoder, and the fault samples and feature vectors are combined as the input of the broad learning system. The broad learning system is trained based on the error precision step update method, and the system is used to the fault type identification. The simulation results of the thyristor fault diagnosis of the three-phase brid

The aim of this paper is to analyze the influence of adding serial inductance in AC side of the ‎‎3ph -6 pulse bridge rectifier on the reduction of harmonic distortion rate. A simulated model ‎with serial inductance was analyzed. The 3-phase 6-pulse diode bridge rectifier was chosen ‎because it corresponds to the operation of the 6-pulse thyristor bridge rectifier at maximum ‎load (while keeping the angle α = 0). Both the total harmonic distortion (THDi) and the ‎power factor (PF) for the circuit have been measured. The results obtained of the THDi has ‎been recorded for four values of serial

Excitation system is one of the most important parts of synchronous generators, where the system functions to provide dc power to the field generator coil. Iin this study, a static excitation system consisting of transformers and connected thyristors in bridge configuration has been implemented in synchronous machines that operate as 206,1 mva capacity generators, 16,5 kv using the help of matlab simulink r2017b software. By adjusting the load given to the generator, variations in excitation currents can affect the amount of output voltage generated by the generator so that it can increase and

This paper presents a versatile, low-cost real-time control platform with embedded isolated inputs and outputs for direct usage in electrical applications. The inputs correspond to voltage and current measurements, while the outputs are digital signals with isolated power supply. The validation for the platform considers the implementation of the power electronics topologies where the control algorithms are implemented in Simulink. The topologies are the interleaved three-phase buck converter, push–pull converter, H-bridge, and thyristor-based AC load controller. The control for them involves

In electrified liquefied natural gas (LNG) plants variable frequency drives (VFDs) interact with turbine-generator (TG) units creating torsional vibrations known as sub-synchronous torsional interactions (SSTIs). Torsional vibrations can be dangerous for an LNG plant when they involve torsional instability. The stability of an LNG plant depends on the plant configuration and on the number of TG units and of VFDs. In such peculiar configurations stability cannot be achieved acting of the VFDs control system. Alternatively, dedicated equipment is needed to damp the torsional vibrations. In this
