Introduction

This article delves into the complexities of the Ningde Power Plant's solid waste utilization project. We will explore the role of industrial automation in optimizing the plant's operations and ensuring reliable power generation.

Project Scope and Objectives

The Ningde Power Plant, equipped with 2x600MW and 2x660MW coal-fired generating units, has undertaken a significant project to effectively utilize solid waste. A 360,000-ton fly ash processing system has been implemented to produce high-quality fly ash products.

Control System Architecture

The heart of the plant's automation system is a robust combination of Siemens PLCs and Advantech industrial PCs, seamlessly integrated with the Intouch SCADA platform. This architecture provides real-time monitoring, control, and data acquisition for critical processes.

Key Control Functions

• Process Monitoring: The system continuously monitors key process parameters such as pressure, temperature, and flow rate, ensuring optimal operating conditions.
• Data Logging: Historical data on temperature is collected and stored for future analysis, facilitating trend analysis and troubleshooting.
• Equipment Control: The system provides precise control over various equipment, including oil pumps, motors, and valves, ensuring efficient and safe operation.

Unique Features and Innovations

One of the standout features of this system is the implementation of a redundant oil pump system with automatic failover. This ensures uninterrupted oil supply to critical equipment, enhancing system reliability. Additionally, the system incorporates interlocks with the mill to prevent potential hazards.

Conclusion

The Ningde Power Plant's control system serves as a prime example of how industrial automation can be leveraged to enhance operational efficiency and environmental sustainability. By carefully selecting hardware and software components and implementing advanced control strategies, the plant has achieved significant improvements in its operations.
