AC 800PECHigh performance control systemFor high power rectifier applications

High performance application with extremely fast control algorithm–The cycle time range of fast control is 100 μs (microseconds).Cycle to seconds for long-term operating transients-requirementsSpecial control equipment.This is why we designed AC 800PEC, which extends ABB's famous automation technology to deal with the algorithm application program of high-speed power electronics and other processes. Can you imagine a process loop, a moment below 100 μs? We can-we invented a new generation of AC 800PEC controllers to accomplish it. Dual-core processor unit combines these high-speed manipulation and low-speed processing, which makes the technology further manipulated. The task is usually performed by an independent PLC (programmable logic controller) unit. Embedded in the robust and sensitive architecture, the integrated standard communication AC 800PEC is unique in the field of industrial process controllers. AC 800PEC is the ultimate product close to high requirements. AC 800PEC has the following unique combination characteristics for severe application: short cycle time, as low as 100 μs high processing, fast communication and I/O programming can be completed through optical fiber links:-The system engineering conforming to IEC61131-3 uses the words of ABB to control the generator. Two languages-compact and professional version-product and control development uses MATLAB /Simulink based on model design, which easily bridges the gap from simulation to performance, and is completely integrated into ABB Ability system. 800xA uses FPGAs creatively and sensitively, and the protocols and application functions contained in it do not need to create rated processors. The life cycle of optical communication is longer than that of industrial-grade hardware without moving parts, and it is easy to upgrade to a strong reliance file system, which is not affected by post.

AC 800PEC software provides a special range of control and communication functions at three performance levels. We have developed the following software packages to support the rectifier application of each of our specific high-power products. Aluminum uses the AC 800PEC equipment controller. The AC 800PEC main controller communicates with the controller through PEC-PEC optical fiber. The optical link (100 μs) can be mastered independently of the control unit to allow urgent operation (full smooth current control, in urgent mode, there is no AC 800 PEC, Only used in combination with DCS800 pre-magnetization) software that can contain predictive maintenance functions such as open circuit, overcurrent, undervoltage and overvoltage maintenance package-newly developed OPC (open circuit maintenance) independent PLC (programmable logic controller), controlled shutdown in maintenance events with AC 800PEC main controller function or independent maintenance panel as main equipment, You don't need to travel immediately → reduce the disturbance to you. Potline load swing detection and load shedding application software integrates the function of on-load tap changer quick tapping function. In order to avoid DC current overload disturbing the special potentiometer based on AC 800PEC series, the maximum power can be adjusted (permed)-to avoid excessive power consumption, and support your generator to adjust your process with stable maximum DC voltage.

Chemical use: OLTC step compensation control in lubrication process-IDC step compensation of lubrication current and current change during boosting. OLTC power factor compensation can include predictive maintenance function. Software maintenance package includes:-DC over-current maintenance-communication over-voltage and under-voltage maintenance-communication phase imbalance maintenance -12-pulse system imbalance maintenance system. DC grounding fault detection can be realized by 3-volt meter with SIL 3-level process pulse. The voltage at the input of the module loop crosses the voltage sag. Electrolytic extraction industry (copper and zinc): IDC current step compensation, which is used for the current change during lubrication and boosting. The power factor compensation of OLTC can include predictive maintenance functions: DC overcurrent maintenance, communication overvoltage and undervoltage maintenance, communication phase imbalance maintenance, 12-pulse system imbalance maintenance system, main DC current control unit of parallel rectifier, DC open-loop detection during operation, DC open-loop maintenance, and the graphitization process of DC power supply in graphite electrode factory requires a lot of DC voltage and current change power supply. Providing a constant DC power supply to the process does not take into account the changing process resistance-probably due to the very fast cycle time AC 800PEC controller. Ability to add customized process recipes and modify them in order on the operation panel to meet specific customer requirements. After adding the corresponding formula, the rectifier follows the predefined DC current, DC voltage and maximum allowable power set point, including all necessary chart-specific maintenance functions.

Function scalability: You and your process define what you need, and your process defines the required function level. Several pre-equipped software packages can easily obtain simple projects. The processing cycle time of distributed control system is as low as 1 millisecond. Using slow I/O to program man-machine interface in control generator is as low as 1 millisecond. Using interface programming in slow and fast I/O control generator to support almost all common fieldbus hardware time stamps can be provided to programmable logic controller as low as 1 millisecond on request. Using fast and slow I/ O programming in the control generator, the programmable automation controller cycle time is as low as 100 μs, fast and slow I/O MATLAB /Simulink programming and any speed process interface AC 800PEC of the control generator supply two types of I/O-fast, and it is very slow. The fast I/O system includes the time when reading and writing operations need less than 1 ms, while the slow I/O system covers the speed of more than 1 millisecond. The fast I/O system is dedicated to AC 800PEC, which uses equipment connected only by optical fiber links, and has obvious advantages compared with the electric concept: the fast communication I/O equipment between the controller and the transmitter has high electromagnetic interference resistance and no potential connection, and the slow I/O module of ABB S800 system can be added to any equipment, depending on the project in detail.

Multifunctional and reliable AC 800PEC is suitable for any application to be seamlessly integrated into factory control. In today's demanding market, it is necessary for operators to provide not only the best performance, but also transparency. In this respect, AC 800PEC offers a wide range of possibilities. Integrated communication ensures transparent factory-wide data exchange and control-from overall factory control to independent processes. ABB system 800xA and powerful AC 800PEC controllers promise the high-grade solution of unified automation and seamless integration of process control system throughout the factory.

AC 800PEC is very suitable for harsh environment-AC 800PEC has a huge installation foundation because the AC 800pec manipulator is used in different ABB solutions, which makes it possible to extract long-term life cycle experiences. Traction with particularly harsh environmental conditions is one of the most important applications of AC 800PEC. The manipulator can work in a wide temperature range (-40 to+70 C), and the oscillation conforms to the traction specification. A compact solution is an integrated unit that responds to the limited demand and promises to deal with it, and all I/O are in the same compact hardware device. Reliability is necessary-AC 800 PEC power supply is generally generated, and the excitation system used for generator control in high reliability power plants is the first requirement. Because of the short process cycle, the traditional concept of redundancy is no longer applicable. If the modular architecture of AC 800PEC is not so, it will only greatly reduce the overall complexity system, but the redundant subsystem will also provide reliability improvement. If there is a problem with a subsystem, the main controller switches to other subsystems, and these subsystems are shared so that the overall mission can still be completed. If there is something wrong with the main controller, the second controller is in a hot standby state. Accuracy of the best quality–The most demanding function of -AC 800 pec for industrial process rolling mills is thickness control. By using the powerful AC 800PEC manipulator, a new thickness control solution for cold rolling mill is based on MIMO (Multiple Input Multiple Output) control concept. The advantage for customers is that the thickness deviation is improved by up to 50%.

The AC 800PEC tool is used for all AC 800PEC.The controller handles the operation.
