Tag: IS200DTAIH1ACC

The IS200DTAIH1ACC is a turbine control panel for a variety of industrial applications, such as power generation, oil and gas, chemicals and pharmaceuticals. It is a microprocessor expansion board manufactured and designed by General Electric as part of the Mark IV control System. A microprocessor expansion board is a device used to extend the functionality of a microprocessor-based system. In turbine control systems, microprocessor expansion boards can be used to add additional input/output (I/O) functions to the control system. Turbine control systems typically use a microprocessor to control the operation of the turbine, and microprocessor expansion boards can be used to add additional I/O capabilities to the system, allowing more sensors and actuators to be connected. For example, the microprocessor expansion board can be used to add additional temperature sensors to the turbine control system.

IS200DTAIH1ACC is a top-level file design algorithm, written in Verilog HDL language. Its main functions include signal acquisition, processing and control, as well as fan start and stop, load regulation and protection operations.
First of all, IS200DTAIH1ACC has strong signal processing capability. Through the A/D control module, the ADS8364 chip can be controlled for sampling, so as to obtain real-time data of voltage and current. This data is then fed into the Clarke transform module and the three-phase PLL module to perform the necessary transformations and demodulation.
Secondly, IS200DTAIH1ACC has powerful control function. The DSP outputs ud and uq through PI regulator, and after Park conversion, uα and uβ are obtained and sent to SVPWM module. In this module, an accurate PWM waveform can be generated by sector judgment and vector movement time calculation to control the operation of the turbine. In addition, in order to prevent the overmodulation phenomenon from distorting the output voltage waveform, the IS200DTAIH1ACC is equipped with an overmodulation module using the proportional reduction algorithm. At the same time, a dead zone control module is added to avoid direct passage between the upper and lower bridge arms. The addition of these modules significantly improves the stability and reliability of the system.
