Notes: Conclusions 1. Periodic operational checking of the central controller of the GAPC system will make it possible to prevent incorrect operation of the system, to reduce operating expenses, and to shorten the shutdown time of the GAPC system for conducting tests. 2. Simplified automatic checking will make it possible to establish the fact of malfunction of the GAPC system when the assigned and actual power of the hydrostation do not correspond. 3. Continuous automatic checking and protection of the GAPC system will make it possible to eliminate a spontaneous change of the power of the hydrostation both when troubles occur in the technological systems of the units and in the GAPC system, in which case operational checking without shutdown of the GAPC system is provided. 4. Each of the examined methods of technical diagnosis of the active power control system of a hydrostation has its own shortcomings and advantages, and its selection for the given hydrostation should be examined individually.

Notes: Conclusions 1. The improvement of the ACSTP of a hydroelectric plant is an ongoing complex program of economic, technical, and organizational measures that are related on an organizational basis to improvement of the operational organization of a hydroelectric plant or network of hydroelectric plants, both active and under design. These measures are still more effective with the simultaneous improvement of control systems of higher-standing levels. 2. Domestic and foreign experience with the improvement of automatic control systems for active hydroelectric plants indicates that the greatest savings due to these measures is realized where the hydroelectric power plants are united organizationally into networks of plants. 3. To create objective conditions for increasing the efficiency of control systems, it is expedient to build complex production subdivisions responsible for the development, design, implementation, and operation of control systems in design organizations, at the hydroelectric power plants, and regional power administrations (PÉO). 4. One of the fundamental deficiencies encountered in planning plant organization and control, which supports the introduction of highly efficient automatic control systems, is the absence in the plans of alternate schemes for the organization of the operation of networks of hydroelectric plants, and also promising organizational structural linked with the system being designed for control of a hydroelectric plant (network of plants). 5. In revising the GOSTs for a ACSTP, it is necessary to eliminate existing inaccuracies that create the potential for their contradictory interpretation, e.g., in determining automated systems for the control of projects as a function of the presence of electronic computers in their makeup. 6. The solution of new problems in the ACSTP of a hydroelectric plant (unit optimization, technical equipment diagnostics, adjustment of unit assignments in accordance with active capacity, analysis of the efficiency of utilization of the water passing through the hydroelectric plant, etc.) is restrained, on the one hand, by the impromptu character of the methods employed for solution of these problems, and on the other, by the absence of a standard base for water usage, and apparatus for regulating the parameters and conditions required by the specifics of the project, by the incompleteness of the individual technological systems, and by the inadequate reliability of certain control facilities, including the electronic computer. This will also impede the widespread introduction of microcomputers in control systems. 7. The introduction of new effective centralized-control facilities (new systems) requires the mobile rebuilding of the organizational structures of the traditional facilities put together under operating conditons, and specialization.
