Advanced Technologies

Deploying eight core technologies, integrating various intelligent

Core Technologies

HiOC integrates atime series prediction model and deploys eight proprietary core technologies.It incorporates algorithms such as machine perception, data mining, model training, and reinforcement learning. Through automatic optimization,artificialintelligence,alamnavigation, and othetechnologies,it predicts addmand and ensures optimal boiler combustion efficiency and production safety. Ultimately,it achieves dynamic load inteligent optimization and coordination,helping thermal power enterprises achieve the goals of energy saving, efficiency improvement, workforce reduction, and quality enhancement.

Multivariable Adaptive Optimization Controller

The multivariable adaptive optimization controller is designed for complex and dynamic industrial processes:
■It integrates multiple technologies, such as predictive control, sof measurement, and big data self-learning. to achieve intelligent decoupling.
It is capable of real-time adjustment of control parameters, adapting to fuel type changes in the fuel control loop and solving issues related to mismatched preset model parameters.

Intelligent Imitation of Human

Intelligent imitation of human control technology is developed to adapt to the special scenarios in industrial sites,and it mainlyhas twofunctions:

· Overcoming the limitations of regulation equipment by using software strategies to simulate human operations, thereby maximizing the automatic engagement rate.
■ For control lops with large time delays, dynamic acceleration and overdrive are used to simulate humanlike operations, minimizing response time as much as possible.

Intelligent Coordination

The intelligent master pipe coordination control system is based on energy balance (the balance between steam production and steam consumption), achieving decoupling control according to external load changes, automatically optimizing the load command allcation for each boiler quickly eliminating steam production and consumption imbalances. The system presets 3 load distribution modes, and operating personnel select based on demand.

Distributing the total load, calculated dynamically, evenly to each boiler in operation according to the coordination requirements

Automatically calculating the pipeline resistance \mathsf{K}{=}8λ!/(\uppi29\mathsf{d}5) based on the principle of minimizing pipeline loss, and distributing the load intelligently

The operator manually sets the distribution coefficient according to the boiler operating conditions, and the total load is distributed based on this coefficient.
