Alstom Grid Automation provides utilities and industry with the mission critical software systems and equipment needed to manage the flow of electricity in transmission and distribution grids, ensure grid stability and to protect and control substations.
It enables integration of all protection, control, measurement and monitoring functions within a substation, and additionally provides the means for interlocking and inter-tripping.
Aletom can be done as previously using the front port serial connection of the relay, or now optionally over the Ethernet connection if preferred. Calculate unique number based on both the function and layout of the logic.
Otherwise the locus of the 3 single phase loops have passed through the polygon indicating loss of synchronism and the sign of R is different from the point of entry ; then an out of step is detected. To do this, when all required changes have been entered, return to the column heading level and press the key. When negative sequence polarising is used, the relay requires that the Characteristic Angle is set.
The technical manual include the previous technical documentation, as follows: These are provided to give an indication that the relay is in a healthy state. For equipment with pin-terminal connections, the threaded terminal block for current transformer termination does NOT have automatic CT shorting on removal of the module. X, the following elements are available: Neither ALSTOM, its officers or employees accept responsibility for, or should be taken as making any representation or warranty whether express or impliedas to the accuracy alsotm completeness of such data or the achievement of any projected performance criteria where these are indicated.

Reported measurement values are refreshed by the relay once per second, in line with the relay user interface. The generic aletom event model is based on p44 concept of an autonomous decentralization, providing an efficient method allowing the simultaneous delivery of the same generic substation event information to more than one physical device through the use of multicast services. It is denoted SK4. These types of VT design allow the passage of residual flux and consequently permit the relay to derive the required residual voltage.
Level 2 As level 1 plus: Qualified personnel are individuals who: Power swing blocking is automatically removed after the Unblocking Delay with typical settings: However, certain faults may arise which can remain undetected by such schemes. Series faults will not cause an increase in phase current on the system and hence are not readily detectable by standard overcurrent relays. The use of an apostrophe in the logic eg. The MiCOM Agile P also incorporates enhanced circuit breaker failure logic with additional protection functions such as dead zone and overcurrent.

Real time monitoring and control of the power system Improved accuracy, latency and reporting rates versus SCADA data Flexible communications Graphical programmable scheme logic PSL eases protection scheme creation, and avoids the need for external logic controllers. Medium duty terminal blocks are used for the digital logic input signals, the output relay contacts, the power supply apstom the rear communication port.
The apstom for the rear port must be specified when the relay is ordered.
This provides good earthing at all joints giving a low impedance path to earth which is essential for performance in the presence of external noise. The Fourier components of the input current and voltage signals are stored in memory alsfom that they can be accessed by all of the protection elements algorithms.
Overhead lines can be hundreds of kilometres in length. The single line diagram for the alwtom or a subset of the substation, along alsotm relevant data, may be generated via the configuration tool, aided by integrated graphical icons. The power supply board also provides the RS electrical connection for the rear communication port. The digital input signals are opto isolated on this board to prevent excessive voltages on these inputs causing damage to the relay’s internal circuitry.

Note that for the P, P and P relays, zone timers tZ1 to tZ4 are started at the instant of fault detection, which is why they are shown as a parallel process to the distance zones. The network is then said to be “healthy” before the fault occurrence. User-friendly graphical user interface for a,stom creation and visualization of curves either by inputting formula or data points.
