CONTROL OVER INTEGRAL SHIP ELECTRIC POWER SYSTEM (IEPS)

摘要

FIELD: power engineering.;SUBSTANCE: data on the state and IEPS parameters and that on screw propeller drive and other consumers and ship navigation conditions are processed to calculate forecast load variation. Starting including forestalling, outage and actuation for parallel operation of generators are controlled with die allowance for their required quantity sufficient for supporting of IEPS operation, ship motion control parameters and navigation conditions. Minor consumers ON/OFF control is executed to ensure the efficient operation of generator units and higher quality of supply voltage. Dynamics of acceleration and deceleration of screw propeller and its drive is controlled subject to ship motion, navigation conditions, current and forecast electric power and quality parameters. Dynamics of turn of steering house, if any, is controlled depending on generated and forecast power of generator units.;EFFECT: fuel savings, fast response and manoeuvrability, higher energy quality.;1 dwg
