2 TRIPPING MATRIX DEVICE 7UW50 As of Tripping Circuit Management Unit or Non-electric Protection Device The integrated CPU module can help to record the status of matrix module. Any new information can be accessed locally via PC or sent to remote control centre via the serial protocol IEC over the electrical RS485 interface. APPLICATION 2 NON-ELECTRIC PROTECTION DEVICE Based on the above functionalities, the tripping matrix device 7UW50 can be used as the non-electric protection device too if no CFC function is required.. Fig. Front illustration of Tripping Matrix Device 7UW50 APPLICATION TRIPPING CIRCUIT MANAGEMENT UNIT The tripping matrix device 7UW50 is a component of Siemens numerical generator protection system. The biggest advantage of the hardware tripping matrix module is to provide a transparent, visible, simplified and easily programmable facility for the combination of protection functions and output commands to variable tripping objects. The tripping matrix device 7UW50 is developed to manage the tripping circuit of generator protection system for large power station block. With the integrated matrix module, the tripping scheme can be freely modified with the most flexibility to fit for different field requirements, i.e, the tripping objects of the protection function can be easily changed on site via the operation of logic plugs to assigned column on front panel. The device 7UW50 is integrated with signaling modules for all matrix inputs from various protection units. Each input can be indicated by signaling relay with at least potential-free contacts which can be routed for alarming to DCS, FR, RTU, etc. The device 7UW50 is also, for all matrix outputs to different tripping objects, integrated with tripping modules. Each tripping relay has at least 2 potential-free contacts which can be routed for tripping to GCB, Field CB, HVCB, etc. The non-electric tripping commands (e.g, from Heavy Buchholz relay) can be directly connected to the inputs of matrix module. After the matrix programming, the assigned outputs will initiate the tripping relays which are routed to respective tripping circuits. Note that the tripping behavior is immune to any transient disturbance due to the heavy initial power consumption (approx. 8.2W). DESIGN AND CONSTRUCTION Modules inside the device: - Matrix module - Signaling module - Tripping module - Power module - CPU and communication module - LED indicating module Matrix Module The matrix module comprises input module and output module. Inputs (column) and outputs (row) are reliably connected via diode connectors (logic plugs). The inputs are equally divided into two groups. Both groups are arranged one over the other (see Fig.2) and electrically connected internally. To cater for the different requirements and applications, the matrix is equipped with 4 For local alarming purpose, latched LEDs are installed to indicate all matrix inputs and outputs. They can be locally reset via front RESET button or remote reset via binary input. Siemens SIP /

3 types, i.e, 54x (see Fig. ), 0x (see Fig. 4), 54x2 (see Fig. 5 left) and 0x2 (see Fig. 5 right). That is, e.g, matrix module 54x has 54-input (each group with ) and -output. Fig. Fig.4 Diagram of matrix module 54x Diagram of matrix module 0x Fig.2 Matrix Module Types of 54x and 0x are in principle designed to serve for tripping circuit management while 54x2 and 0x2 for non-electric protection. It could be mixed in some case. Signaling Module Each signaling module is designed for matrix inputs, that says up to 9 signaling modules are required for the max. 54-input. Each input is indicated by two grouping contacts and one individual contact. Even, the st and rd signaling relays on each signaling module separately have one additional individual contact. All contacts are potential free. Tripping Module Each tripping module is designed for matrix outputs, that says up to 2 tripping modules are required for the max. -output. Each output is interpreted by two individual contacts. Even, the st and 2nd tripping relays on each tripping module separately have two additional individual contacts. Tripping module with type of lockout relay is optional. In this case, the module TRL (MLFB position th= 2 or 4) should be selected. Note 2/ Siemens SIP

4 that the 5th tripping relay on each tripping module have been exclusively designed to be with un-lockout relays even in this case. The contact form of tripping relay can be all in Normal Open (NO) type or some in Normal Close (NC) type which are respectively defined by ordering code (MLFB position th= or 2). All contacts are potential free. External tripping relays can also be used if one of tripping modules is equipped without tripping relays (see Fig.). In this case, the module OUT (MLFB position = 0, or 4) should be selected. CPU and Communication Module CPU module is to take over the task of internal SOE and communication. The status of matrix module will be monitored and recorded. The messages can be locally accessed via Port C over PC, or remotely accessed by two control centers via two RS485 Ports of B and B2 over protocol IEC IRIG-B is implemented for time synchronization via Port A.. The specially designed software GPAcom is to serve for parameter setting of communication ports, time synchronization and local access to the device. LED Indicating Module Overall local alarming on the status of matrix module, power module and CPU module is done by LED indicating module. Latched LEDs is used for indicating the matrix module. Fig.5 Diagram of matrix module 54x2 and 0x2 Power Module LEDs and CPU are supplied by power module. Note that the signaling module and tripping module are directly powered by station s control voltage. That is to say, these modules can properly work even if the internal power module failed. Module s Interaction The interaction diagram among the matrix module, signaling module and tripping module is schematically shown in Fig.. Note that beside the remote signals, the LED indicators and SOE are also initiated by signaling relays. The similar situation applies to tripping module. To be noted that CPU module has no influence to modules of matrix, signaling and tripping. Siemens SIP /

OPERATION Connection between the protection functions and matrix module is implemented via master plugs (red), while the connection between matrix input and output via logic plugs (black). The plugs are plugged into the front panel of the matrix after the plexiglass front cover is removed. A reset button is used for resetting all memories. This can be directly done on the plexiglass front cover. The memories (LEDs) can also be remotely reset via a binary input. TRIPPING CONCEPT FOR NUMERICAL PROTECTION Siemens SIPROTEC numerical protection units used for generator-transformer block incorporate an integrated software matrix. The required tripping objects by one protection function can be directly programmed over software DIGSI. If several multifunctional units are used for the protection system, the tripping contacts of the individual relays to the same tripping object must be connected in parallel (see Fig. 7). This is the tripping concept with software matrix. If master tripping relays are inserted between the binary outputs integrated in the protection units and the tripping objects, the tripping combination can also be externally implemented. The master tripping relays then take over the task of decoupling the signals, multiplying the contacts of the integrated binary outputs and realizing the tripping combinations via the assignation of tripping signals (GCB, Field CB,...) to form tripping commands from protection functions. Therefore, the binary outputs of the individual relays with the same required tripping consequence must be connected in parallel to activate the same mater tripping relay, and the contacts with the same tripping objects of various master relays must be externally connected in parallel to the respective tripping circuit (see Fig. 8). This is the tripping concept with master tripping relays. If a variable arrangement of the tripping combinations is required for large generator unit, the hardware matrix described here can be very helpful. The binary outputs of protection functions from several protection units are to be directly routed to the inputs (rows in Fig. 9) of hardware matrix, meanwhile the tripping relays to the outputs (columns in Fig. 9). The operating contact of tripping relay is to be connected to the respective tripping circuit. This is the tripping concept with hardware matrix. The easy, fast and flexible combination of inputs and outputs on front panel of the device is visibly executed by the diode logic plugs. Note that at most tripping objects can be connected regarding the matrix output up-limit. 4/ Siemens SIP
