Abstract—

The paper considers the experience of upgrading a unified electric power system (UEPS) with an electric propulsion system (EPS) of the diesel–electric icebreaker Kapitan Kosolapov. The upgrading is caused by the need to replace the UEPS–EPS equipment and extend the icebreaker’s service life. Technical inspection of the main UEPS–EPS electrical equipment has been carried out before the upgrading. When developing a technical project, a comparative circuit analysis and technical solutions have been carried out and the required electrical calculations have been performed. As part of the upgrading, the main diesel generators, controlled armature circuit rectifiers, and reversible controlled rectifiers of the propulsion motor excitation circuit have been replaced. A microprocessor controlled EPS system has been developed. An integrated control system for the technical means of the vessel has been introduced. Mooring, sailing, and ice tests of the icebreaker have been carried out. In the course of testing the UEPS, the quality of electricity in the ship’s network, stability of the stand-alone and parallel operation of the diesel generators, and distribution of active and reactive loads have been checked. When testing the EPS, the quality of transient processes of the propulsion electric installation has been assessed. The transient acceleration, deceleration processes, and reversing of the propeller motor have been oscilloscoped. The successful upgrading and testing allowed the service life of the Kapitan Kosolapov diesel–electric icebreaker to be extended.

升级柴电破冰船时设计和测试电力船舶发电厂的经验

摘要-

本文考虑了使用柴电破冰船Kapitan Kosolapov的电力推进系统 (EPS) 升级统一电力系统 (UEPS) 的经验. 此次升级是因为需要更换UEPS-EPS设备，延长破冰船的使用寿命。升级前已对主要UEPS-EPS电气设备进行了技术检查。在开发技术项目时，已经进行了比较电路分析和技术解决方案，并进行了所需的电气计算。作为升级的一部分，主柴油发电机、控制电枢电路整流器和推进电机励磁电路的可逆控制整流器已被更换。已经开发了微处理器控制的EPS系统。引进了船舶技术手段的综合控制系统。破冰船的系泊、航行和结冰试验已经完成。在测试 UEPS 的过程中，检查了船网供电质量、柴油发电机单机和并联运行的稳定性、有功和无功负荷的分配情况。在测试 EPS 时，已经评估了推进电气装置的瞬态过程的质量。螺旋桨电机的瞬态加速、减速过程和换向已在示波器上显示出来。成功的升级和测试，延长了产品的使用寿命 和螺旋桨电机的反转已经过示波器。成功的升级和测试，延长了产品的使用寿命 和螺旋桨电机的反转已经过示波器。成功的升级和测试，延长了产品的使用寿命Kapitan Kosolapov柴电破冰船将被延长。
