CCU1000 Central Control Unit
Description The CCU1000 relay master provides a simple and technically complete solution for the integration and automation of electrical substations as well as industrial plants. When IEDs in a substation or industrial plant are linked to a CCU1000 unit using GE Power Substation Automation software, the protection and control capabilities are extended to the whole system, as it provides tools that can completely manage any substation/plant from the dispatching center. The system formed by the CCU1000 and the protection relays is fully distributed, as every unit receives all signals coming from its operation area, and it is able to perform associated functions, as well as to retrieve all necessary states, measurements, events and records. The CCU1000 retrieves and manages all this information, making it accessible both to the local operator and the remote control center. The system is scalable, as the user can define anytime the desired level of integration, at a plant level or integrated with a SCADA or DCS master.
The CCU1000 architecture and communications network are designed to be easily adapted to any size, reliability and redundancy level requirement. Besides, there are architecture solutions available for single/multiple system concentrators, HMIs and communication channels at any level.
GE Power application software, runs on the CCU1000, allows the user to extract the plant/ substation databases, so that it is possible to obtain all the required information, making it very easy to analyze the system operation and the associated records at any Engineering center.
The CCU1000 is accessible in many different ways, including graphical screens of the substation/plant single-line diagrams, programmable screens, IED status, integrated alarms and event records, metering and oscillography records.
The system can be remotely accessed by using a remote network access software. This access can be restricted to limited personnel and it incorporates safety measures to prevent unauthorized access.
The execution of operations is controlled and protected by passwords, and the unit allows to execute operations and trigger automatisms from the unit face plate. Besides, the CCU1000 incorporates software tools that allow the user to access any IED from a networked PC, or using a monitor, keypad and mouse directly connected to the unit.
The Scada functionality provided by GE Power software offers the possibility to connect to a remote SCADA or DCS in the plant or to any dispatch center. This connection will be enabled using IEC 870-5-101, IEC 870-5-104, OPC or MODBUS RTU communication protocols. External protocol converters can also be used if required.

System Architecture with CCU1000 This figure shows the typical communications architecture used with CCU1000.
Thanks to the communication network, the CCU1000 processor incorporates the internal variables of all the connected protection units. Automatisms such as tap changers, automatic substation recomposition, recomposition after underfrequency load shedding, reactive control, etc. can be implemented using the PLC incorporated inside the CCU1000.
The information retrieved from the protection relays by the CCU1000 is available in the local substation network, as the CCU1000 operates as a standard OPC (OLE for Process Control) information server. This way, any graphic HMI from a different manufacturer using this technology and operating as an OPC client can be connected to the CCU1000. GE Power monitoring and control software operates as an OPC client, providing additional functionality, such as file management, protection setting change management, and with operation capability of several OPC clients inside the same communications network.
The variable simulation tools available in the GE Power software package, make these automatic functions programming tasks extremely easy.
nals sent from the satellite network, with 1 ms accuracy. This real accuracy is obtained thanks to the fact that the CCU1000 operative system works with real time features. The CCU1000 offers a modem as an option, that provides remote access to the system, independently from the remote control access, allowing the user to perform remote maintenance, charge and control tasks, usually performed by the Engineering departments of Utility companies.
In order to synchronize the time labeling of the events generated by the CCU1000 with those generated by the protection relays, the CCU1000 can incorporate a GPS module that will synchronize the date and time with sig-

User Interfaces The CCU1000 front plate includes a pushbutton to set the substation management in local or remote mode. When the local mode is selected all remote operations will be forbidden. On the other hand, when the remote mode is selected, only commands originated on the CCU 1000 will be executed. The CCU1000 incorporates 16 LED indicators, 15 programmable, whose default configuration is as follows: 1. READY. The CCU1000 is on and communicating with protection relays. Once the unit is powered, this LED will remain red until the internal application of CCU1000 takes control of the unit. In this moment, the LED will turn green. 2. ALARMS. There is an active or not acknowledged alarm in the substation/plant. 3. MAINTENANCE. The CCU1000 is in maintenance mode. In this mode, we can modify the unit configuration. For accessing this operation mode, we need to connect the CCU1000 to a monitor, keypad and mouse, and modify it when the unit is powered. 4. PLC BLOQ. The PLC software is internally blocked. Automatisms are blocked. 5. BUSY. The CCU1000 is busy sending commands to the protection relays. 6. FREE

Maintenance and operation tasks can be performed from a portable PC, connecting it directly to the Ethernet input or to an available Hub in the substation. With this type of connection, we have access to the whole GE Power software functionality.

With OPC and several standard clients. The CCU1000 is a standard OPC server, and it can operate with different graphical OPC clients, being able to perform many configurations for different control centers, located in different network places, accessing simultaneously all the information retrieved by the CCU1000 from the protection relays. With this type of connection, we have access to the whole GE Power software functionality. Additionally, we can use a graphical environment different from GE Power, if the OPC standard connection capability is incorporated.
As an option, the CCU1000 can include an internal GPS module and modem.

Redundancy The CCU1000 capability for redundant connection guarantees continuous system operation in the event of a component failure, and offers system availability of 100%. The following figure shows a typical redundant architecture diagram with CCU1000. The proposed system is designed to ensure safe and continuous system operation even in the event of a failure inside the protection and control system. There are two main types of redundant configuration: Hot-Standby and in parallel.
■
Hot-Standby Operation
In this first case, one of the CCU1000s is active and operates as master, maintaining communication with protection relays, while the second CCU1000 is in standby mode, i.e. it is ready to activate communication with the relays. Both units are communicated via a redundant RS-232 link. If any of the two CCU1000 fails, the second unit will retake communications and become master unit of the system, while the failed unit would switch to standby mode. This operation is automatic and managed by both CCU1000.
■
Operation in Parallel
In this operation mode, both CCU1000 are in service simultaneously communicating with protection relays and the remote control. If one of the units fails, the second CCU1000 would continue communicating with the rest of units in the system. In this type of configuration, protection relays need to incorporate two communication ports, one for each master device, or a networked port that allows simultaneous access from several master devices, as in the case of UR and F650 relays. In the case of protection relays that provide only one port, an external converter can be used to allow access from both master devices.
Technical Specifications TYPE TESTS
HOT-STANDBY OPERATION The first CCU1000 unit handles communcation with the protection & control IEDs and telecontrol. The second CCU1000 unit is in standby mode. If the first CCU fails, the second unit will automatically take control of the communication with the IEDs and telecontrol.
PARALLEL MODE Both CCU1000 units are communicating with the protection & control IEDs and telecontrol. In case of one-port asynchronous IED, a multimaster converter from Ethernet to Serial is required
