During mains failures, DER (Distributed Energy Resources) should stay operated and connected to the grid to support decreasing mains voltage, by feeding reactive power. Woodward has developed various Intelligent Electronic Devices, which are in compliance with international grid requirements (Grid Codes), to avoid electrical or mechanical damage to the DER in these cases.
Distribution & Protection
Interconnection / Mains Decoupling
From the generation via transmission and distribution down to the load, Woodward's feeder protection relays protect the entire power chain throughout different voltage levels.Modern communication and linking to systems are the basis for economical and efficient applications of your operating components. For nearly every communication network Woodward offers you various protocols like Modbus® RTU and Modbus® TCP, Profibus® DP, IEC 60870-5-103 and IEC 61850.
To ensure day-to-day electrical induction motors keep processes running, and to maximize the motor’s operating life, Woodward offers a variety of highly-adaptable Intelligent Electronic Devices to protect them against inadmissible electrical, thermal, or mechanical stress.
Transformer protection and maintenance is essential for a reliable energy supply. Woodward’s intelligent electronic devices with perceptive algorithms protect your electrical equipment against damages that are costly and difficult to replace.
Woodward’s Intelligent Generator Protection Relays provide a broad scope of primary and backup protective functions, from overcurrent protection to generator differential protection. This highest availability is a key factor for reliable power generation.
Line Differential Protection
Woodward offers line differential protection with fiber optic communication, because it is the best way to protect an overheadline or cable. Speed is important for differential protection because it is the most selective protection. Since communication between the devices occurs via fiber optic connections, data transmission is not only especially fast, but also extremely safe.
Our protection relays are to be used according to European directive 2011/65/EU Article 2, Point 4-for the described purposes/installation types.
