Electrical and C&l System
A. Automatic control strategy, protection logic optimization. Generally the contractor makes configuration commissioning as per conventional thinking to configuration design of DCS control strategies for the control systems during construction and operation period, after the unit running for some time, their respective different characteristics and original configuration design and protection logic shortcomings and deficiencies will show up, so the security and stability of the unit can not be guaranteed, which requires adjustments and optimization in later stage, we can offer the excellent services in such respect.
B. Power module, controller, I/O modules and other accessories for ECS, DCS, DEH, TSI, TDM, MEH and MTSI systems.
C. PLC module of chemical water, ash handling, coal handling, condensate polishing and other auxiliary control system, such as: power module, controller, I/O module and spares etc.
D. Electrical and C&l field measurement devices, detection devices and control actuators, such as: current transformers, voltage transformers, disconnectors, circuit breakers, power distribution panels and cabinets, motors, electric/pneumatic actuator, (pressure, flow, temperature, liquid level, material level) transmitters, flow orifices and so on.
