Optimization of Diesel-Driven Generators in Continuous Power Systems of Essential Consumers

摘要

Today's trends in the development of engineering and technical systems of various facilities stipulate for higher requirements to the reliability of essential consumers' power supply and the electrical power quality in all operation modes. At the moment, to execute these requirements, continuous power systems including, as a rule, static uninterrupted power supply sources and diesel-driven generators are used. The latter are necessary to ensure the required durability of the system autonomous operation. Resolving the problem of diesel-driven generators optimization in the continuous power systems of essential consumers providing for high reliability indicators is impossible without taking into account the peculiarities of the combined operation of DDGs and static UPSes, both in transient and steady operation modes. This problem can be stated as a discrete programming problem the resolution of which will help to avoid unreasonable economic costs as well as possible technical failures occurring when the parameters of the considered system components do not match. To resolve it, the authors developed a mathematical model where the capital investment minimum or the minimum of the reduced annual costs taking into account operating costs are chosen as optimality criteria. The obtained research results are implemented by means of the software and brought up to the engineering level.
