Power Plant Auxiliary System
Besides BTG Island, one complete power plant also has a lot of related auxiliary equipment including water/steam system, electrical system and control system as the three main auxiliary systems (coal handling system, ash & slag handling system could be considered as scope of Boiler Island). Based on our company's experience on overseas projects, there are more problems arising from the auxiliary equipment/ materials side instead of BTG side during power plant installation & operation since the auxiliary equipment/materials are numerous and miscellaneous. Then, the minor problems sometimes seriously affect the whole project schedule. This is because contractor and owner always pay more attention to the BTG equipment, but neglects the auxiliary equipment& auxiliary systems.
Our company thinks highly of the importance of auxiliary equipment and auxiliary systems all the time. We have the detailed calculation on auxiliary equipment /materials selection from the very beginning of design. We always adopt the higher side rather than the lower side for the standard equipment technical parameter selection. The same happens for the class and standard selection of auxiliary materials. Considering the quantity of equipment interfaces, we always reserve some margins for the amount of piping and standard parts so as to assure no failures at all during site erection.
Control System and Instrumentation
Small & medium sized power plant usually adopts more advanced centralized control method, which carry out the BTG centralized control on the thermal equipment and auxiliary system in the main building as well as the electrical system (generator main loop, HV and LV service power of main building). One CCR is set in the main building. Water treatment station and coal handling system adopt Central Control (PLC) together with local control; meanwhile it can realize the communication with DCS. Main equipment in the water intake pump house are incorporated into DCS, and the balance of equipment adopts local control; Ash & slag handling system is also incorporated into DCS, and some equipment adopts local control; Water intake pump station sets I/O branch station, and adopts the combination method of local and centralized control.
