It covers the special demands of renewable energy plants regarding reliability, robust-ness, flexibility, and remote accessibility in an optimal way. Based on an existing generator control system ap-proved for marine applications and used in thousands of ships and land-based power stations over the last 25 years, DM-4 Hydro matches the special demands of harsh environments and far-away-locations faced in the land-based decentralised renewable energy generation. The control of a hydro turbine is designed for un-manned operation. The user interface provides full information to the user and allows an efficient diagnosis and a fast reestablishment of the operation locally as well as remotely. Properties The system DM-4 Hydro covers the following functions as a standard: Measurements: - Generator voltages three-phase L1, L2, L3, N - Mains voltages three-phase L1, L2, L3, N - Currents L1, L2, L3 - Active power per phase/total - Reactive power per phase/total - Active and reactive energy counter - Operating hours - Circuit breaker operations counter - Temperatures and pressures at the turbine - Measurement values of the plant Data sheet DM-4 Hydro DEIF A/S Page 3 of 8 Protection functions: - Mains protection - Vector jump - df/dt (R.O.C.O.F.) - Support of a hardware safety chain with reset function - Electrical protections generator over- and un-dervoltage, over- and underfrequency, current asymmetry, overload, reverse power, mini-mum power, overcurrent, thermal overcurrent, overexcitation, loss of excitation - Overspeed - Wire-break proof supervision of the breaker position - Supervision of hydraulic oil pressure - Supervision of room temperature - Supervision of pressure of the water inlet line - Emergency stop - Water level monitoring for de-rating of genera-tor by dropping level - Supervision of main valve - Supervision of control valve(s) - Tooth-on-tooth supervision of turbine runup speed - Level supervision in external oil containers (lube oil, hydraulic oil) - Configurable inputs for fault messages (e.g. for digital auxiliary contacts of automatic cut-outs and motor-protection breakers) User interface: - Display of all measurements as graphics and in numbers - Visualisation of the states of the protections - Trending function - Logbooks with more than 200 entries with time stamps each - Adjustment of parameters - Multi-user function with standard hardware as touch screens, laptop computers for direct access (USB, TCP/IP) - Remote access (TCP/IP) - “Living” P&I diagrams on the screen shows changes and states of components in graphics - Operation of the plant - Maintenance calls after operating hours, adjustable Control functions: - Fully automated turbine start/stop - Synchronisation with voltage adjustment and time supervision - Speed governor with speed ramping function - Power ramp function for smooth start and stop - Prerun and postrun of auxiliaries - Load reduction function due to generator tem-perature, control valve position and room air temperature - Operation of motorised circuit breakers - Analogue power setpoint - Peak shaving - Water level controlled operation - Voltage adjustment and CosPhi control - Control of the room temperature - Support of a safety chain - Demand signal to a hydraulic power pack Typical Scope of Delivery: - DM-4 Hydro hardware - Touch panel PC if desired - Example wiring diagram - I/O list - List of error messages - Commissioning check list - P&ID example - Handbook Data sheet DM-4 Hydro DEIF A/S Page 4 of 8 System components The whole DM-4 Hydro system consists of only three modules in a unique way. Each module contains its own processor, therefore it works independently. All three modules will be delivered in a standard indus-try rack. Each rack contains one PCM module and a selectable number of SCM modules (mainly 1) and I/O modules (variable). Available standard sizes: - 24 TE for 2 modules - 42 TE for 3 to 5 modules - 60 TE for 6 to 8 modules A standard configuration for a hydro turbine generator covers e.g. the following components in a 42TE rack: - 1 PCM 4.3 - 1 SCM 4.1 - 3 IOM 4.2 PCM 4.3 The PCM 4.3 is power supply and main control module of the DM-4 Hydro system with a module width of 8TE. It is mounted leftmost in the rack. It supplies all other modules in the rack and controls the data exchange on the backplane. Furthermore, it bears the control unit with the application software and the following interfac-es: - 3 CAN interfaces 125...1000 kBd - 1 RS485 interface 9600...38400 Bd - 1 ARC-net interface 2.5 MBd - 1 USB interface - 1 Ethernet 10/100 MBd - 1 serial port (9600...38400 Bd TTL) for a GSM modem connection (SMS alarming) In a plant control system, the module behaves as cen-tral control. The application software is located in this module; therefore it determines the overall functionality of the plant. SCM 4.1 The SCM module is used for the measurement of elec-trical values and execution of fast protections and con-trol functions. It measures voltages up to 690V AC (three-phase) directly (L1 L2 L3 N generator, L1 L2 L3 N mains/busbar). It performs an independent syn-chrocheck function, can directly trip the circuit breaker and evaluates the breaker feedbacks. Three-phase currents are captured via CTs (1 A or 5 A sec). The SCM module offers a certified measurement of voltage, current, frequency, active power, reactive power, and phase angle at class 0.5 between 40 and 70 Hz. The measurements are transferred to the PCM module once per period where further protection functions, trending, and logging are located as a part of the appli-cation software. IOM 4.2 The IOM is a multi-functional I/O module for connection of different sensor types. It also interfaces to other systems by standard analogue and digital signals. The module offers: - 6 inputs for temperature, Pt100 in 2-, 3-, or 4-wire technique or thermocouples type K (NiCr/Ni) - 4 analogue inputs -20...+20 mA with 12 bits resolution - 4 analogue outputs for transducer signals or setpoint signals, burden up to 500 Ohms, out-put range -20...+20 mA, resolution 10 bits for connection of speed governors, AVRs, or fre-quency converters. - 12 digital inputs, 9…36V DC with common potential for sensors switching to plus or mi-nus. - 4 individual galvanically separated digital inputs, 9…36 V, for the evaluation of sensor or pulse signals (1.25 MHz sampling rate). - 10 digital outputs with external power supply 9…36V DC, push-pull outputs with a stable operation against GND and against supply voltage up to 200mA continuously. The out-puts are continuously short-circuit proof and furthermore protected against thermal over-load. - Each board possesses an own galvanic sepa-ration between analogue I/O, digital I/O and in-ternal potential. This avoids loops through several boards. Data sheet DM-4 Hydro DEIF A/S Page 5 of 8 User interface The DM-4 Hydro system shows a unique user interface that allows running the operating terminal function on any standard Windows PC like industrial touch-panel PCs and laptop computers. All possibilities for local and remote access wire-less or wire-bound can be used because the connection can use Ethernet or directly USB to the PCM module. If several users are online at the same time, they see the same graphical layout, each one on his own com-puter. The remote start can be blocked by a manual switch on the switchboard panel door for safety rea-sons. This way – under maintenance – the remote access allows for diagnosis and visualisation, but the start can only be performed locally. The user interface uses a browser principle with univer-sal, plant-independent browser software. The infor-mation that has to be displayed is therefore defined on application level. Because of this principle, the data is always consistent. The PCM module is the “Server“, whereas the different users are “Clients”. Buttons on the fully graphical user surface allow easy access to all visualisation pages. The pages are grouped by themes and can be reached fast and easy either using the menu structure or a central navigator. The status field is structured in the same way on all pages. It shows the state of the plant and – if active – the most important error message. Graphical elements like remote position indicators, bar graphs, pointer in-struments for electrical values (kW, A, V, CosPhi) give a full overview of the occurrences that take place at turbine, generator, mains and plant. The protections are visualised on special diagnostic pages together with the actual states, measurements, limits and running timers.
