Excitation Devices

Excitation Device Overview

The excitation device is an electrical control device that controls and regulates the excitation current in the excitation system of synchronous generators, in addition to the excitation power supply.

The excitation system is an indispensable part of the power plant equipment. The excitation system includes excitation power supply and excitation device, of which the main body of excitation power supply is exciter or excitation transformer; excitation device is made up of regulating screen, control screen, demagnetizing screen and rectifier screen according to different specifications, models and requirements.

The excitation device is used to maintain the voltage at the end of the synchronous generator at a given level under the normal operation of the power system, and also has the functions of forcible magnetization, demagnetization and demagnetization. It also has a rectification function for those using the excitation transformer as the excitation power source. The excitation device can be provided separately or as a supporting supply for power generation equipment.

Small and medium-sized hydraulic power generation equipment has been implemented to export product quality licensing system, without obtaining export quality license products are not allowed to export.

Types and specifications of excitation devices

Excitation devices are mainly divided into two categories: electromagnetic type and semiconductor type. Electromagnetic excitation devices are mainly used in excitation systems with DC or AC exciter as the excitation power source, while semiconductor excitation devices can form a static (or rotating) rectifier excitation system together with the exciter, or a static excitation system with the excitation transformer.

At present, China's exports of excitation device models, the scope of application and the main components (such as the table) each production plant in addition to supplying stereotypes, but also according to the needs of users to design and manufacture.

Can you imagine a process with a cycle time of less than 100 μs?

We can – and we’ve built the AC 800PEC to achieve it

High-performance applications with extremely fast control algorithms – cycle times that range from 100 microseconds for fast control loops to seconds for long-term operational transients – require specialized control devices .

That is why we have designed the AC 800PEC, extending the capabilities of ABB’s well-known ControlIT automation technology to handle the very high-speed algorithms of processes such as power electronics applications . We’ve even gone a step further: now, a single processor unit combines these high-speed controls with the low-speed process control tasks usually carried out by separate PLC units .

To facilitate the implementation of control algorithms, the AC 800PEC can be programmed using MATLAB® / Simulink® – the code is automatically generated from the model and can be downloaded without manual interaction .

Embedded into a robust and flexible system structure with integrated standard communication, the AC 800PEC is unique in the field of industrial process controllers .

The AC 800PEC, the ultimate approach for high demands

The AC 800PEC provides the unique combination of features

required in demanding applications:

− Short cycle times down to 100 μs

− High processing power

− Fast communication and I/O

− Programming tools:

− System engineering with IEC61131-3 languages using ABB’s Control Builder, either as Compact or Profes- sional version

− Product & control development using MATLAB® / Simulink® for model-based design, easily bridging the gap from simulation to implementation

− Full integration into ABB’s System 800xA

− Innovative and flexible use of FPGAs to include protocols and application functionality in the devices without creating additional processor load

− Optical communication

− Industrial grade hardware with no moving parts

− Long life cycle, easy upgrading

Built to control power – in industry, utilities and traction

ABB is a globally active company with full process know-how in a wide field of industrial, utility, traction, marine and other applications . As a result, the AC 800PEC is a key controller for ABB’s own range of industrial applications, and also for third party products and systems .

The AC 800PEC is an efficient and flexible controller family. Thanks to its short cycle times, fast I/O, high processing power and advanced control using MATLAB® / Simulink® , the

AC 800PEC:

− Increases process quality and output

− Saves development and engineering costs − Reduces the energy consumption of your products − Shortens time-to-market for your development project − Saves headcount and resources in engineering and

software development

− Enhances Return on Assets (ROA)

The modular structure of the AC 800PEC control system means it can adapt to any application size, from the largest industrial plants and propulsion systems down to very compact products where space and cost are critical .

All over the world, many thousands of processors are now proving their worth in a wide variety of extremely demanding applications .
