Integrated Automation System for Power Plant
Brief introduction

This integrated automation system mainly applies to the small and medium hydropower or thermal power plants with unit capacity of 100MW and below, in which the microcomputer protection, monitoring and control systems are integration or relatively independent operation. Adopting completely open hierarchical distributed network structure and meeting the international standards, the system is a new generation of microcomputer automation system based on Windows/Unix operation platform and object-oriented design. This system can easily fulfill the automation on operation supervisory, control adjustment and operation management of the overall plant to achieve the aim of 'No person on duty, few person on guard'. This system is in the leading level in China with advantages of high performance cost ratio, advanced technology, friendly interface and simple operation etc..
Typical application
These drawings are only as a reference for the system structure, local LCU equipment type and quantity depending on plant size and functionality requirements.

Active-standby hot standby mode (single CAN Bus)
Double network mode (single network is used usually)
