Subjects
Mining engineering. Metallurgy, TN1-997
Abstract

The structures of systems with high-voltage cascade frequency converters containing multi-winding transformers and low-voltage low-power converters connected in series at each output phase of the load are considered. Low-voltage blocks contain three-phase diode or active rectifiers, DC capacitor filters, single-phase stand-alone voltage inverters and block disconnecting devices in partial modes (in case of failure when part of the blocks are disconnected). The possibilities of operation of cascade converters are determined, equations for correcting tasks to units in partial modes are given, tables of correction of tasks with estimates of achievable load characteristics are proposed. The results of experiments on the model of a powerful installation with a cascade frequency converter are presented, confirming the possibility of ensuring the symmetry of the load currents when disconnecting part of the blocks and the asymmetry of the circuit.

Abstract

To cut the amount of machine time spent on designing systems with electric machines and semiconductor converters, it is proposed to describe processes using smooth current and voltage constituents. It is also proposed to use dual system models that combine the simulation using smooth components of curves with the simulation of systems by interconnected subsystems. This allows reconciling the requirements on the speed and accuracy of calculating long-time processes. An example of creating a dual solid-state drive model with a PMAC motor is provided.

Abstract

Рассмотрены структуры систем с высоковольтными каскадными преобразователями частоты, содержащими многообмоточные трансформаторы и низковольтные маломощные блоки преобразования, соединенные по выходу последовательно в каждой фазе нагрузки. Низковольтные блоки содержат трехфазные диодные или активные выпрямители, конденсаторные фильтры выпрямленных напряжений, однофазные автономные инверторы напряжения и устройства отключения блоков в частичных режимах (при выходе из строя и отключении части блоков). Определены возможности работы каскадных преобразователей, даны уравнения для корректировки заданий блокам в частичных режимах, предложены таблицы корректировки заданий с оценками достижимых характеристик нагрузки. Приведены результаты экспериментов на макете мощной установки с каскадным преобразователем частоты, подтверждающие возможности обеспечения симметрии токов нагрузки при отключении части блоков и несимметрии схемы.

Abstract

Models of Synchronous Generators with PWM DC-DC converter and Self-Excitation Systems have been designed. Calculations have shown that the unipolar PWM DC-DC converter in some modes shortly excludes from the voltage regulation process. The bipolar PWM converter effectively affects the generator and consequently enhances the system operation speed. The bipolar PWM converter uses the energy recovery in exciter as a short-circuit protection. The unipolar DC-DC converter uses explosive fuse and dumping resistor as a short-circuit protection.

Abstract

The features of the start-up of asynchronized synchronous compensators (ASC) are described. The characteristic of the PU-6-05 starters for the ASK-100 compensators produced by “Elektrosila,” branch of the JSC “Silovye macshiny,” is given. Problems of determining the position of the rotor, operations in the artificial and natural switching zones, and the processes of synchronizing the compensator with the power network and slowing of the power plant are considered.

Abstract

A breadboard model of the store of kinetic energy with an asynchronized electric machine and a cascade frequency converter in a rotor circuit is created. The converter is executed on the basis of a single-phase blocks connected to the network through transformers and connected from the rotor consistently in each phase. Transformation blocks contain single-phase active rectifiers and voltage inverters. They provide a bilateral exchange of energy between the network and the rotor. A control algorithm is developed and experimentally checked up by the single-phase active rectifiers, allowing to minimize an exchange of signals between blocks.
