　general information

Product number: SYN5201-4281

ABB Model Name: Synchronizer 5

The operation principle of synchronizer 5 is that the synchronization and parallel processes can be divided into command generation

Enter the following block command to generate and calculate the necessary lead angle av, and the parallel command must be measured through this command due to the shutdown time delay. This operation ensures that the voltage difference OU (amplitude), slip s (frequency difference – contact closure at the correct time. If a reaches the average value of 1. rence), and phase angle a are all necessary for parallel connection. These values are commanded by two measurement signals formed during the negotiation release (CHK release). Under synchronous conditions, U1 and U2 (see illustration, lff). The permanent parallel release time during the adjustable monitoring period, tsup, and CMD also release matching considerations without taking the lead. The voltage and frequency matching function can reduce the voltage synchronization check mode (parallel monitoring) by only measuring and monitoring the voltage or turbine governor in the synchronization check mode. The function block is active. Output relay monitors parallel release under negotiation conditions. This function compares the actual value to its set value if all conditions are simultaneously filled with fuel. Advice on single channel or dual channel? Not every synchronous system needs to be structured according to the above pattern. Synchronous rotating 5 single channel synchronous devices provide a high degree of security and are often used in practice. However, security can significantly increase the system through dual channels. These two channels – where the hardware and software structures are different and the same fault occurs simultaneously. Additional costs and damage caused by incorrect parallel connection.

Secondly, redundant synchronization system? Usually, two redundant synchronization systems are installed so that in the event of a system failure, the other can be used to improve availability. This second system is usually designed for manual Timing belt or no synchronous check. In addition, through SYNCHOTACTO 5, ABB offers two automatic dual channel systems in a single enclosure to avoid manual synchronization. The advantages of this solution are: – No engineering and wiring costs for the second system – Further improved safety due to all four output contacts, typically operating in series – with minimal use of manual synchronization systems.

Catalog Description: Synchronizer 5ABB’s SYNCHROTACT ® Automatic synchronization of generators and transmission lines is achieved through the IEC 61850 communication protocol. In any power plant, the generator must be parallel to the transmission line, while in a substation, two synchronous lines must be parallel. The IEC61850 protocol is processed with an additional processor, while maintaining perfect reliability and excellent performance.

ABB will launch its market leading 6th generation synchronous and parallel technology SYNCHOTACT at ABB Customer World Africa in Johannesburg, South Africa from April 10th to 11th, 2018 ® 6。

For over 50 years, SYNCHROTACT has been protecting power plant generators and substation components from the potential destructive effects of current surges caused by circuit breakers closing under asynchronous conditions. SYNCHROTACT ensures the safety of these valuable production assets and maintains the highest level of availability by automatically synchronizing the speed, voltage, and frequency of the generator with the power grid.

SYNCHROTACT 6 includes new and enhanced features to maximize security. It is the only synchronizer with a diverse dual channel design, with two channels located in the same SYNCHROTACT device to minimize wiring, ensure perfect working compatibility, and reduce debugging costs for end customers. If one channel fails, the other channel remains open to ensure reliability. The robust design of this device complies with IEC 61508 SIL2 safety standards.

The number of parameter sets has increased from 7 to 20, allowing up to 20 different circuit breakers to be synchronized through a single SYNCHROTACT 6 device. Complies with IEC 61850 Ed. 2 communication standards, SYNCHOTACT 6 meets the most stringent requirements.

Since its launch, over 22000 SYNCHROTACT devices have been sold, equivalent to about 10% of the global synchronous equipment market. All main generators of the world’s largest hydroelectric power plant, the Three Gorges Dam in China, are equipped with SYNCHROTACT synchronizers.

We are pleased to announce the launch of this extraordinary sixth generation product, “said Kevin Kosisko, General Manager of ABB’s Power and Water Business. SYNCHROTACT has long been the preferred synchronizer for global utilities and generators, thanks to its excellent safety and redundancy. It provides our end customers with the highest availability and lowest possible total cost of ownership

SYNCHROTACT 6 is a part of ABB’s excitation and synchronization equipment products for the power generation industry. This product is the most comprehensive and mature in the market, covering power requirements from minimum to maximum, covering all power generation applications.

ABB Power Generation&Water is a leading supplier of integrated power and automation solutions, with unparalleled experience in collaborating with the energy and water industries, bringing them better operations and sustainable development.
