英语翻译
A solution to this system problem is the use of fast-acting
solid state circuit breakers.Power semiconductors such as
IGBTs and IGCTs are commercially available in voltage and
current ratings that are compatible with the requirements for a
ship distribution system.The microsecond response time of
power semiconductors allows them to limit fault current to
low levels,and consequently limit the system energy that must
be managed (i.e.dissipated).Such breakers can have
“universal” configurations suitable for both DC and AC
applications,and can be scalable for a wide range of ratings as
typically required for a ship power distribution system.Their
use can result in a superior power system that enables the full
capabilities of a power converter-based ship distribution
system.
Solid state circuit breakers can also offer advantages when
used in traditional ship power systems.Their fast response
provides current limiting,so that faults are limited to a
selected level rather than the level dictated by the supplying
generators.This offers particular advantages for medium
voltage parallel generator lineups where peak available fault
current can exceed the ratings of typical electromechanical
breakers.Among the benefits of low (limited) fault currents
are low magnetic and thermal stresses on distribution
components (e.g.cables,bus bars),and low energy delivered
to faults resulting in a safer overall system with reduced
component costs.By limiting fault current to low levels (e.g.
2x rated) the time required to isolate a fault will also be short,
typically less than 1ms as opposed to many AC line cycles
(typically 100ms for a MV system).The short duration of
fault events results in minimal line voltage disturbances seen
by loads on the common distribution bus.The ability of loads
to “ride through” a fault without interruption provides
improved performance without a major investment in
protective hardware such as an ABT or UPS.
This paper describes the primary interruption characteristics
of conventional electromechanical circuit breakers.It also
describes topologies and performance requirements (and
limitations) of solid state circuit breakers and their benefits to
new ship power systems.

固态断路器用于传统船舶电力系统时也可带来好处.其快速响应可提供电流限制,使故障水平局限于选取的水平内,而不是发电机所决定的故障水平.中压并联机组的峰值有效故障电流可能超出典型机电断路器的额定值,因而固态断路器可为中压并联机组带来独特的好处.低（有限）故障电流可对分布组件（如电缆、母线）产生较少的电磁和热应力,并且较少的能量消耗在故障上,从而使整套系统更安全,而且组件成本更低.将故障电流限制在较低水平（如2倍额定值）也可缩短隔离某一故障所需的时间,与许多交流线路循环（一般一个MV系统需要100ms）相比,一般少于1ms.故障事件的持续时间短可将线路电压扰动降至最低,这一点可通过共用分布总线的负载看出.负载可以无干扰地“通过”故障将提高系统性能而无需投入大量资金购置ABT或UPS等保护硬件.
本文描述了传统机电断路器的主要中断特性,还描述了固态断路器的拓扑结构和性能要求（及限制）,以及为新型船舶电力系统带来的好处.
