The consolidation of unit power capacities and the complication of technology with the objective need to reduce the number of attendants (operating personnel) are conditions that determine the need for further centralization of control and establish new requirements for control systems (CS) and technological processes (TP) at electric power plants. The problem of developing a technological system having an optimum automated control system (ACS) has emerged in this connection. This problem is solved by many members of design and operating organizations.Beginning in the mid-1930s, active work involving the automation of hydroelectric plants --the development and implementation of automated and automatic control systems for the technological process using various technical means, including, use of computer techniques beginning in the 1960s --has been performed in our country.Dwelling briefly on the very concept of ACS, we entered our practice at the close of the 1960s. State standards (GOST 19675-74, 16084-75, 20913-75, 17195-76, etc.) treat ACSTP as a system containing complex of technical facilities --CTF --including computer-technlque facilities. This course, on the one hand, makes it impossible to classify any control system realizing the necessary technological algorithms on the basis of any technical facilities, but without electronic computers, as an automated control system, and Section 2.6 of GOST 20913-75 "ACSTP development stage" permits the absence of programmable computer-technique facilities in the system. Previous concepts were "automatic systems for controlling technological processes in industry" (GOST 17195-70) and "a system for the automatic control of technological processes (SACTP) in industry" (GOST 16084-70). These GOSTs, which have now been revoked, interpreted more definitively the role played by the electronic computer in control systems built around both electronic computers, and also other technical facilities. True, attempts are again being made to correct matters concerning the concepts "automatic control systems using electronic computers" or "automation using computer techniques," but all this is still just an open discussion of active "rigid" GOSTs; the need for revision and more precise definition of these GOSTs has already been brought to light.t Many technological complexes, e.g., pumping, compressor, and diesel plants, certain electric power plants, and other facilities are completely automated, and function without permanent operating personnel; at the present time, however, their control systems remain unnamed, and there are no All-Unlon standards for the development of these systems.The maneuverability of hydroelectric power plants and the possibility of regulating river flows at the majority of these plants are their most important qualities. It is impossible to utilize these qualities of the hydroelectric plant to the fullest extent and solve problems dealing with improved efficiency and reliabillty of plant operation, reduction in the number of operating personnel, and imp...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
