Assuring the availability of energy on land and at sea as well as safe energy supply solutions through network protection and control systems – this is what stuckeGROUP products and solutions offer. 

Made in Germany – we manufacture our products, including development, exclusively in Hamburg. Our multifunctional protection and control systems offer engine control as well as comprehensive protection functionalities for generators, motors, transformers and other feeder lines, besides distance line differential and grid protection. Functionalities include power management, DP system logics, arc protection, reactive power undervoltage protection, grid decoupling and power plant control for low, medium and high voltage systems, for gas and diesel engines, gensets and power units as well as hybrid systems. They stand out for reliability and longevity, and we hold spare parts for all product generations on stock. 

Our customers are for example system integrators, shipyards, shipowners and -managers, designers, owners and operators of power plants, sites for generation of renewables or of emergency energy systems. Customer focus, a profound understanding of customer needs and prompt availability are important for us. 

The project department offers our customers planning, design, production, installation and commissioning of complete and tailor-made switch and control cabinets for low and medium voltage solutions.

SYMAP® is a flexible microprocessor-based digital protection device for use in low, medium and high voltage power systems. Because of its integrated protection functions and human machine interface capabilities it is an efficient and cost-effective solution for all types of switchboards. With three powerful microprocessors SYMAP® offers comprehensive protection functions for generators, motors (synchronous and asynchronous), transformers, power lines and distributions. 

All protection functions can be activated simultaneously. With SYMAP® five main breaker controls can be activated with all necessary functions such as display, control and blocking for optimal breaker manage ment. A small integrated PLC allows individual functionality, such as interlocks from controlling functions. 

For flexibility in commissioning and during use, both digital and analog outputs can be used to connect the SYMAP® control unit to main switchboard controls. Additionally, a variety of serial interfaces with different kinds of protocols can be used for communication between SYMAP® units and the central control system. For diagnostics and monitoring, SYMAP® has three microprocessors that supervise each other, providing a watchdog system. Important functions are laid out in a double redundancy combination, operating independently with the second processor. Connected separately, an optional unit for short circuit protection operates parallel to the SYMAP® device and will do so even if the entire voltage fails.

SYMAP® is easy to program and operate. A large graphic LCD with optional LED indicators conveys important data such as position of all connected breakers, parameter settings, and event histories at a glance. Graphics and measurements are displayed side-by-side on the LCD, so that the user does not have to switch between pages. The entire programming of SYMAP® can be done with the keys on its front panel or by using a notebook. Using a notebook offers the advantage that stored parameters can easily be applied to other SYMAP® units. Either way, easy programming is guaranteed and on-site visits by the manufacturer’s engineers during commissioning is not required. SYMAP® provides four hotkeys placed underneath the LCD to access four main groups of values, namely »Meters«, »Alarm«, »Process« and »Breaker Control«. The user can press the hotkeys to scroll through pages of information. The hotkey »Meters« provides detailed information on electric measurement values, counters for active and reactive power and working hours. The hotkey »Alarm« displays all active alarms, event log and blockings. »Process« shows all process data such as the synchronization display, motor thermal indication and a counter of breaker operations. Under »Breaker Control«, up to five breakers can be accessed and controlled. When programming breaker controls the user has access to various layout configurations via a library. Programmed blockings remain active when manual control of the breaker is used. Each of the highlighted breakers in the LCD can be further controlled by the keys »O« and »I«. For security, access to SYMAP®’s parameter and breaker control data is protected by a code system, accessed by a password.

Terminal connections All connections to SYMAP® are made with terminal plugs on the back of the device, allowing the device to be exchanged easily. 

Analog input for measurement 

SYMAP® provides inputs for analog sensors at the rear of the device. If terminal plugs for the CTs are disconnected, the circuits will be linked automatically so there is no disconnection in the CT circuit loops. A total of 17 analog inputs for current and voltage transformers are used for protection functions. The following list shows possible connections for current transformers (CT) and potential transformers (PT): •  3 x CT inputs for feeder current •  1 x CT input for ground current •  3 x PT inputs for feeder voltage •  3 x PT inputs for 1st bus bar voltage •  3 x PT inputs for 2nd bus bar voltage •  1 x PT input for ground voltage 

Communication 

SYMAP® can serve as the main bay controller for the power management system or substation system. The following list shows the station system items available through  SYMAP®: • remote supervision •  remote control •  remote parameter setting •  central registration of measured and calculated values •  central event logging •  central fault recording, analysis and logging •  plant power management 

Communication interfaces 

SYMAP® provides communication ports available with the following interfaces and protocols: •  1 x RS 232 on the front panel for programming and data output •  1 x RS 422/485 port • 1 x PROFIBUS DP (RS485 or fiber optic port) •  MODBUS RTU •  MODBUS TCP (RJ45 or fiber optic port) •  IEC 60870-5-103 (RS485 or fiber optic port) •  IEC 61850 (RJ45 or fiber optic port) •  CANBUS 1 (communication between devices as power management system, breaker control interlocking) •  CANBUS 2 (engine control interface: MTU, VOLVO, DEUTZ etc.)
