A distributed control system (DCS) is a computerized control system for a process or plant usually with many control loops, in which autonomous controllers are distributed throughout the system, but there is no central operator supervisory control. This is in contrast to systems that use centralized controllers; either discrete controllers ...
A DCS control room where plant information and controls are displayed on computer graphics screens. The operators are seated as they can view and control any part of the process from their screens, whilst retaining a plant overview. Process control of large industrial plants has evolved through many stages. Initially, control was from panels ...
PCS—Power conversion system, electric power conversion. Plant Control System. PCT—Programmable Communicating Thermostat (electricity), Production Conformity Test; PD—Preliminary Determination; PDC—Phasor data concentrator. See description in phasor measurement unit article.

DG/DG# – diesel generator ('#'- means identification letter or number of the equipment i.e. DG3 or DG#3 means diesel generator nr 3) DGA – diglycoamine; DGDS – dual-gradient drilling systems; DGP – dynamic geohistory plot (3D technique) [10] DH – drilling history; DHC – depositional history curve; DHSV – downhole safety valve
The DC solution of an electric circuit is the solution where all voltages and currents are constant. Any stationary voltage or current waveform can be decomposed into a sum of a DC component and a zero-mean time-varying component; the DC component is defined to be the expected value, or the average value of the voltage or current over all time.
Standard OPC databases serve as the communication link to the Distributed Control System (DCS), Hydraulic Power Unit (HPU), and Electrical Power Unit (EPU). The UMCS will communicate with subsea control pods at the wellhead from multiple subsea equipment providers, without disrupting the subsea vendor's native communication protocol.

An OTS uses a dynamic simulation of the process in order to generate the appropriated data to feed an emulation of the plant's control system. The elements of a typical OTS are the following: [1] Dynamic simulation software [1] Process model [1] Instructor interface [1] Control system integration software [1] DCS emulator [1] Replica of the ...
