AI Technical Summary
Existing technologies have insufficient automatic adjustment functions in high-voltage bypass control during the start-up phase of thermal power plants, resulting in a large amount of manual operation and long start-up time. Furthermore, the data acquisition accuracy of traditional DCS systems is insufficient, which cannot meet the requirements of complex operating conditions and can easily lead to increased energy consumption and equipment damage.
A redundant external controller is used to communicate with the original DCS system. Combined with a high-precision main steam pressure transmitter and start-up control loop, automatic control of the high-pressure bypass is achieved. Precise control is achieved through deviation calculation and switching modules, and a redundancy judgment mechanism is set up to ensure system reliability.
It achieves automated control of high-voltage bypass, reduces manual operation, shortens start-up time, improves control accuracy, avoids equipment damage, and saves fuel consumption.
