Operating efficiency of hydraulic structures, organization of inspection, and certain results of observations on the hydraulic structures of the Krasnoyarsk hydroelectric plant

Abstract

1. In order to increase the efficiency and provide for a modern level of operation of such large-scale structures as the Krasnoyarsk hydroelectric plant, it is necessary during design to develop a special section in the plans which is devoted to problems associated with the organization of the operation of hydraulic structures and their inspection with consideration given to requirements set forth in the scientific organization of labor. The following should be included with the basic problems that require solution in this section of the plan: development of a scheme for the preventive-repair maintenance and conveyer servicing of hydraulic structures; development of means and systems for remote monitoring and signaling; development of centralized-control systems for hydraulic structures with provision for a maximum of facilities with which to conduct observations; automatic processing of the results of observations with development of a special subsystem for monitoring hydraulic structures in the automatic control portion of the power system; development of an inspection program with consideration given to a reduction in the number of points and in the frequency of measurements, as well as of visual observations during the course of time. 2. An important factor in upgrading the quality of inspection of hydraulic structures may be the development of the most generalized criteria of their reliable operation with a reduction in the volume of observations at individual points in the structures. These criteria should be developed for large hydroelectric plants with the participation of scientific-research organizations. 3. For large hydroelectric plants it is expedient to supplement the composition of inspection with a system of ultrasonic sensors inserted near the surfaces of the structures in the frost-resistant zone to monitor variation in the properties of the concrete during operation. 4. Before turning a hydraulic facility over to the State Commission, it is necessary to inspect and test, as a completed complex, the measuring systems installed to monitor the condition of the hydraulic structures.
