SYN5202a-Z,V221 3BHB006715R0221 同步设备和系统

同步装置广泛应用于有自己发电设施的电站或工业装置，发电机需要与岛线或公用线路并联，或在配电系统中并联。
只有当两个电压近似同步(一致)时，电源断路器才能闭合。否则，可能导致线路运行故障、发电机负载故障，在极端情况下，还可能导致发电机损坏。
SYNCHROTACT®5安全可靠地执行这些功能，无论是作为手动并联的监测元件还是作为独立的全自动同步设备。

命令生成计算必要的超前角αv，通过该超前角并行命令由于关闭时间延迟而必须提前。该动作确保主触点在准确的时间关闭。如果在并行释放(CHK release)的同时α达到αv，则发出命令。在同步条件下，即在可调监测时间内永久并联释放时，也不考虑超前角而发出CMD。

从同步装置来看，期望在正确的时间关闭电源断路器，但如果需要，也可以在允许的任何时间进行并联。
虽然在同步系统中通常采用的两个独立工作通道(双通道系统)的输出触点串联连接，大大提高了防止错误并联的安全性，但这必然会导致可用性的降低。

并非每个同步系统都需要按照上述模式进行结构化。SYNCHROTACT®5单通道同步器件提供了高度的安全性，并经常在实践中使用。然而，通过双通道系统可以显著提高安全性。这两个通道的硬件和软件结构不同，不太可能同时出现同样的故障。与不正确并联造成的损害相比，双通道系统的额外成本可以证明是有益的。

Synchronizing devices are widely used in power stations or industrial installations with their own power generating facilities, where the generators need to be paralleled with an island line or a public line, or in power distribution systems.
Power circuit breakers may only be closed if both voltages are approximately synchronous (coincident). Otherwise, faults in line operation, loading of the generators and, in extreme cases, damage to the generators can result.
SYNCHROTACT® 5 performs these functions safely and reliably, whether as a monitoring element for manual paralleling or as an independent fully-automatic synchronizing device.

The command generation calculates the necessary lead angle αv, by which the paralleling command must be advanced due to closing time delay. The action ensures that the main contacts close at precisely the right time. If α reaches αv at the same time as paralleling release (CHK RELEASE), the command is issued. Under synchronous conditions, ie, permanent paralleling release during the adjustable monitoring time, tsup, the CMD is also issued without taking the lead angle into consideration.

From a synchronizing device, it is expected to close the power circuit breaker at the correct time but also that, if required, paralleling can take place whenever permissible.
Although the series connection of the output contacts of two independently-functioning channels (dual-channel system), which is usual in synchronizing systems, greatly increases security against incorrect paralleling, it necessarily leads to a reduction in availability.

Not every synchronizing system needs to be structured according to the above pattern. The SYNCHROTACT® 5 single-channel synchronizing devices offer a high degree of security and are often used in practice. However, security can be significantly increased by means of dual-channel systems. It is unlikely that the two channels – of which the hardware and software are structured differently – will have the same malfunction simultaneously. The extra cost of a dual channel system can prove beneficial compared to the damage arising from incorrect paralleling.
