Description
Product details:
SYNCHROTACT®5 is the fifth generation synchrotact device sold by ABB Switzerland Limited. ABB’s SYNCHROTACT product is used for automatic synchronization of generators with power lines and parallel of synchronous lines. They are designed for fully automatic operation of dual-channel single-channel systems. Synchronous equipment is used in a power station that requires a generator to be connected to a power line, or in a power station where two synchronous lines are connected to a substation. The power circuit breaker can be closed only when the voltage at both ends is synchronized. Otherwise, there will be a disturbance to the grid, tripping, and impact on generators and transformers. In extreme cases, it can damage both.
SYNCHROTACT 5 ensures safe and secure synchronization whether as a monitoring element of manual parallel or standalone fully automated synchronization units.
The safety and synchronisation of generators and the grid is a primary requirement for such equipment.Safe automatic synchronization is ensured by a compact dual-channel system consisting of two devices with separate hardware and software that are connected in series(see Figure 4).The first channel performs automatic synchronization,and the other is an independent monitor of the first channel(synchronization check).The hardware and software for each channel are designed by different development engineers using different microhandlers to maintain operations free from any possible system bugs.Safe manual synchronization is ensured by a monitoring installation(Synchrocheck)in series with a manual parallel switch(Figure 5).
The SYNCHROTACT 5 application covers the following areas
Application program:
1. The generator and the power line are automatically synchronized in parallel (see Figure 1);
2. Automatic parallel between synchronous and asynchronous lines and bus (see figure 2 below);
3. Automatic or manual parallel monitoring (Synchrocheck) of power lines, generators and non-voltage lines (non-voltage bus), as shown in Figure 3.
