With fast development of computer tech, new PLC has realized functions of DCS products. It has advantages like perfect opening performance, short construction cycle and high performance and low price. Auxiliary control system of thermal power plant gains new innovation and development. It integrates computer tech, information tech and automation tech into one, becomes developing trend of industrial automation.

Power station program control career department, works at industrial automation control system, is one of main business departments of Dalu Tech. It engages in assisting locomotive automation of power station, integrates automation control and information tech into one. Power plant automation project is our most important business trend and gains great achievements in recent years. In recent three years, company achievements have developed greatly. We have accomplished assisting locomotive program control project over 30 items. Our company is a famous power station assisting locomotive program Control Company. The contract amount has developed from over 2,000,000 in 2000 to over 20,000,000 in 2004. With the development of business, there are 16 staffs in our department including four item managers and ten engineers. But there are no more than 4 staffs on the foundation of the department. Technical personnel work at special work of automation control long-term, so they have rich project experience. After five years development of this department, perfect project construction ability is trained. After hard work of so many years, we win good reputation in electric system automation control trade.
Assisting locomotive control system, designed and researched by Nanjing Dalu, is a set of scattering computer control system consisted by PLC. It integrates operation experience of power plant and program control of many years, adopts international advanced and reliable net structure and high quality hardware products and flexible control software. Based on WINDOWS operation platform, the system strengthens real time and expanding. In construction and reformation of thermal power plant program control system, it has wide application foreground.
　　
PLC scattering control system of thermal power plant has following advantages:
1.With most functions of DCS system, but it is safer and more reliable. Compared with DCS system, its cost is low.
2.The system is easily expanded, provides various net structures and is easy to be connected with other systems of power plant.
3.Based on Windows operation interface, this system really Chinesization. It has Chinese operation clues and assists.
4.Multi-media language alerting function.Once warning happens, central station will give sound alerting signal, treating ideas and clue information.
5.Whole system monitoring and self-diagnosing function.
6.Various words supports, safe system and high flexibility.
7.Historical data treatment and report forms treatment function, and send data to ERP system.
