Multilin MLJ Synchronism Check Relay Closing time delay

Closing time delay

The minimum closing time, set at 100 ms, is actually 160 ms, as it is necessary to add the time required by

the measurement units and the operation of the output relays to the set 100 ms. It should be kept in

mind that during the first cycles, from the time of a closure, the voltage is stabilizing both in the line as

well as in the buses and it is no desirable to allow a closure under these conditions. What is more, it is

necessary to take into consideration the response of both the high voltage transformers and the internal

transformers of the relay.

There is also a time for sustaining the permission signal, which always has a fixed value of some 130 ms.,

being the result of a prefixed delay of 100 ms. added to the dropout time of the measurement units (one

cycle = 20 ms. at 50 Hz.) and the deactivation of the output relay (10 ms.).

Minimum settings

Barring any special requirements, it is not recommended to use settings that near the minimum limits for

the relays, (2 V for the voltage difference, 2º for the angle difference), so as to avoid being too restrictive

in close enabling, given the real characteristics of accuracy in the installations, measurement transformers,

etc.

Multilin MLJ Synchronism Check Relay Influence of harmonics

Influence of harmonics

The pillar of the MLJ measurement calculation is the discrete Fourier transform, which is in essence a

harmonics filter. For this reason the voltage and line measurements are not affected by frequencies other

than the fundamental.

The rejection of harmonics is added to the independence of measurements, both magnitude and phase,

relative to frequency signal variations, which is very important in a synchronism checking relay which, by its

own nature, works in variable frequencies.

Given that in power systems, synchronization or synchronism checking is carried out in a steady state, that

is with voltage magnitudes near or equal to the rated value, close enable is not emitted for very low voltages.

Therefore, for voltage of less than 9 volts, the relay stops measuring phase and frequency, not giving

permission to close under such conditions.

The MLJ also offers additional insensitivity to frequency measurement concerning harmonics, since this is

done via a hardware circuit, a zero-cross detector, with an intrinsic harmonics filter. Furthermore, it has a

software filter which operates by double-period measurement, both between the rising and falling edges,

averaging them out and allowing for better performance of algorithm frequency (improving security and

response).

Multilin MLJ Synchronism Check Relay Application

DESIGN CHARACTERISTICS

Measurement accuracy

The differential angle measurement of the MLJ is high precision and is limited solely by errors in available

voltage transformers.

The measurement of the angle is practically independent of the voltage.

In the MLJ the measurement is obtained via a numerical calculation done on digital voltage samples, thus

achieving high precision. This allows for a rating of 2º, which is clearly better than the possible rating using

other technologies.

harmonics filter. For this reason the voltage and line measurements are not affected by frequencies other

Multilin MLJ Synchronism Check Relay DESCRIPTION

DESCRIPTION

The main applications of the MLJ are:

• Connecting a generator to the system.

• Re-establishing the connection between two parts of the system.

• Manual closing of circuit breakers

• Automatic reclosing of a breaker after a relay trip.

The MLJ is a digital synchronism-checking relay that measures bus and line voltages.

It tests:

• Voltage difference

• Frequency slip

• The phase angle between both voltages

The equipment provides an output to enable to close the circuit breaker when all of the values fall within

the set limits and remain there for the duration of time chosen for the setting. In the event that all the

conditions have not been met, after one minute the equipment gives off a signal showing a failure of

closing conditions.

Additionally, it is equipped with DLDB dead line-dead bus, DLLB dead line-live bus, and LLDB live line-

dead bus, making it possible to select any combination thereof through independent settings.

The basic MLJ1000 equipment and the equipment linkable via RS-485 is mounted in a 2-inch module,

compatible with industrial MID systems, or in a 1/8 rack as an individual relay.

Multilin MLJ Synchronism Check Relay Applications

The MLJ is a digital synchronism check relay that measures bus and line voltages,

checking: voltage differences, frequency slip, and phase angle between both voltages

Applications

Generator and network synchronism

Bus or line synchronism check

Protection and Control

Synchronism check operation

Undervoltage supervision

The relay functions in two modes:

• Continuous mode: In this mode synchronism is checked continuously.

• Manual mode: This is activated when voltage is applied through a manually activated input, thus

beginning synchronism control when voltage applied through another digital input for initial checking.

The function of synchronism (with voltage in the line and bus) can be controlled by two undervoltage units,

which allow the synchronism operation when both voltages are higher than the set value.

Additionally, it is equipped with DLDB dead line-dead bus, DLLB dead line-live bus, and LLDB live line-dead

bus, making it possible to select any combination thereof through independent settings.

The basic MLJ1000 equipment and the equipment linkable via RS-485 is mounted in a 2-inch module,

compatible with industrial MID systems, or in a 1/8 rack as an individual relay.
