Feeder Protection and Control 1MRS757468 F REF611 Product version: 2.0 12 ABB 5. Supported ABB solutions The 611 series protection relays together with the Substation Management Unit COM600S constitute a genuine IEC 61850 solution for reliable power distribution in utility and industrial power systems. To facilitate the system engineering, ABB's relays are supplied with connectivity packages. The connectivity packages include a compilation of software and relay-specific information and a full relay data model. The data model includes event and parameter lists. With the connectivity packages, the relays can be readily configured using PCM600 and integrated with COM600S or the network control and management system MicroSCADA Pro. The 611 series relays offer native support for the IEC 61850 standard, including limited binary GOOSE messaging. Compared to traditional hard-wired, inter-device signaling, peer-to-peer communication over a switched Ethernet LAN offers an advanced and versatile platform for power system protection. The implementation of the IEC 61850 substation automation standard enables access to distinctive features including fast software-based communication, continuous supervision of the protection and communication system's integrity, and inherent flexibility for reconfiguration and upgrades. At substation level, COM600S uses the data content of the baylevel devices to enhance substation level functionality. COM600S features a Web browser-based HMI, which provides a customizable graphical display for visualizing single-line mimic diagrams for switchgear bay solutions. The Web HMI of COM600S also provides an overview of the whole substation, including relay-specific single-line diagrams, which makes information easily accessible. Substation devices and processes can also be remotely accessed through the Web HMI, which improves personnel safety. In addition, COM600S can be used as a local data warehouse for the substation's technical documentation and for the network data collected by the devices. The collected network data facilitates extensive reporting and analyzing of network fault situations by using the data historian and event handling features of COM600S. The historical data can be used for accurate monitoring of process and equipment performance, using calculations based on both real-time and historical values. A better understanding of the process dynamics is achieved by combining time-based process measurements with production and maintenance events. COM600S can also function as a gateway and provide seamless connectivity between the substation devices and network-level control and management systems, such as MicroSCADA Pro and System 800xA.

ABB power system example using Relion relays, COM600S and MicroSCADA Pro/System 800xA 6. Control The relay offers control of one circuit breaker or contactor with dedicated push buttons for opening and closing via the local HMI or a remote system, for example, PCM600. By default, the relay is equipped with a single input interlocking scheme. Binary GOOSE messaging can be used in the creation of additional interlocking schemes, such as secured object control (SOC), blocking-based protection schemes or external tripping. These additional protection and control schemes required by specific applications are configured using the local HMI, the Web HMI and the optional application functionality of PCM600. The local HMI and the Web HMI can be utilized for signal configuration, while PCM600 is required for the configuration of GOOSE messaging. 7. Measurement The relay continuously measures phase currents and neutral current. Depending on the configuration, the relay can also measure residual or three-phase voltage. In addition, the relay calculates the symmetrical components of the currents and the maximum current demand value over a user-selectable preset time frame. The measured values can be accessed via the local HMI or remotely via the communication interface of the relay. The values can also be accessed locally or remotely using the Web HMI. 8. Disturbance recorder The relay is provided with a disturbance recorder featuring preconfigured analog and binary channels.The analog channels can be set to record either the waveform or the trend of the currents and voltages measured. Feeder Protection and Control 1MRS757468 F REF611 Product version: 2.0 14 ABB The analog channels can be set to trigger the recording function when the measured value falls below or exceeds the set values. The binary signal channels can be set to start a recording either on the rising or the falling edge of the binary signal or on both. By default, the binary channels are set to record external or internal relay signals, for example, the start or trip signals of the relay stages, or external blocking or control signals. Binary relay signals, such as protection start and trip signals, or an external relay control signal via a binary input, can be set to trigger the recording. Recorded information is stored in a nonvolatile memory and can be uploaded for subsequent fault analysis. 9. Event log To collect sequence-of-events information, the relay has a nonvolatile memory capable of storing 1024 events with the associated time stamps. The nonvolatile memory retains its data even if the relay temporarily loses its auxiliary supply. The event log facilitates detailed pre- and post-fault analyses of feeder faults and disturbances. The considerable capacity to process and store data and events in the relay facilitates meeting the growing information demand of future network configurations. The sequence-of-events information can be accessed either via local HMI or remotely via the communication interface of the relay. The information can also be accessed locally or remotely using the Web HMI. 10. Recorded data The relay has the capacity to store the records of the 128 latest fault events. The records can be used to analyze the power system events. Each record includes, for example, current, residual voltage and angle values, start times of the protection blocks and a time stamp. The fault recording can be triggered by the start or the trip signal of a protection block, or by both. The available measurement modes include DFT, RMS and peak-to-peak. Fault records store relay measurement values at the moment when any protection function starts. In addition, the maximum demand current with time stamp is separately recorded. The records are stored in the nonvolatile memory. 11. Trip circuit supervision The trip circuit supervision continuously monitors the availability and operation of the trip circuit. It provides two open-circuit monitoring functions that can be used to monitor the circuit breaker’s control signal circuits. It also detects loss of circuitbreaker control voltage. 12. Self-supervision The relay’s built-in self-supervision system continuously monitors the state of the relay hardware and the operation of the relay software. Any fault or malfunction detected is used for alerting the operator. A permanent relay fault blocks the protection functions to prevent incorrect operation. 13. Access control To protect the relay from unauthorized access and to maintain information integrity, the relay is provided with a four-level, rolebased authentication system with administrator-programmable individual passwords for the viewer, operator, engineer and administrator levels. The access control applies to the local HMI, the Web HMI and PCM600. 14. Inputs and outputs Depending on the configuration, the relay is equipped with three phase-current inputs and one residual-current input for non-directional earth-fault protection, or three phase-current inputs, one residual current input and one residual voltage input for directional earth-fault protection, or three phase-current inputs, one residual current input, three phase-voltage inputs and one residual voltage input for directional earth-fault and overcurrent protection. The phase-current inputs are rated 1/5 A. Two optional residual current inputs of either 1/5 A or 0.2/1 A are available. The 0.2/1 A input is normally used in applications requiring sensitive earth-fault protection and featuring core-balance current transformers. The three phase-voltage inputs and the residual voltage input cover the rated voltages 60...210 V. The rated currents of the analog inputs can be selected in the relay software. In addition, the binary input threshold (16…176 V DC) can be selected by adjusting the relay’s parameter settings. All binary input and output contacts are preconfigured according to the three configurations, but can be easily reconfigured by setting application-based parameters using the signal configuration functionality of the local HMI or Web HMI. See the Input/output overview table and the terminal diagrams for more information about the inputs and outputs. | | |
