In view of the current in China’s traditional process industry, DCS system as a production process automation control technical means and equipment, its development has been basically mature, while in the next period of time, in various industrial fields will continue to expand the application. Therefore, industry experts suggest that the DCS system not only needs to accelerate the speed of development, but also should improve the quality. Some experts also pointed out that at present, it is not desirable to set certain “thresholds” in the bidding of 600MW unit control system, which is not conducive to the development of domestic DCS system.
In the development process of China’s power industry, the upsizing of the generator set is an inevitable trend, and it has now developed from 300MW to 600MW, and 600MW has become the mainstream, and will soon continue to develop towards a larger 900MW, or even more than 1000MW. To this end, the domestic industrial control system should accelerate the speed of development, must comply with the trend of modern industrial development, and expand the application of new large-scale projects as a basis for development.

Experts believe that although the power generation capacity of 300MW and 600MW units is different, the characteristics and performance of the units are the same, and the requirements for the control system are the same. Therefore, the control system requirements of 300MW and 600MW units belong to the same level, and the control system applicable to 300MW units is also applicable to 600MW units. For 300MW units, including the transformation of old units, the domestic DCS system that has been applied and mature and reliable (generally should be more than two sets) should be encouraged and supported in the application of 600MW units. At the same time, it is emphasized that this is the only way for the development of domestic DCS systems, and the development history of foreign DCS systems also confirms that this is feasible. At present, quite a number of bidders due to the domestic DCS system bias, and set a variety of “thresholds” in the 600MW unit control system bidding, which not only violates the law of scientific and technological development, but also to support the development of China’s industrial control system is also unfavorable.

Experts suggest that in the development process of China’s industrial control system, the production process control system, such as DCS, PLC, FCS and other systems, should be further optimized, and pay attention to the integration of enterprise information, while developing to a higher level and level of integrated control; Research and development of reliable SIS system, MES system, ERP system has become an important direction for the development of industrial control systems.
