INTRODUCTION


3/203

FUNCTIONAL DESCRIPTION

Phase overcurrent (3*50/51) and neutral overcurrent(50N/51N)

Protects the installations against phase to phase and phase

to earth faults, with instantaneous trips (2 levels) and timed

trips (programmable curves ANSI and IEC/BSC, and user

curves).

Phase directional overcurrent (67) and neutral directionalovercurrent (67N)

If the model includes directional overcurrent, the type of

polarization for phase and neutral directional can be

selected by setting:

67 Quadrature polarization Sequence polarization

67N: Polarization by V0

Polarization by V0, I0 (under request)

Sequence polarization

There are models of PL-300 that include a second

directional overcurrent unit.

If the 67N unit is current polarized, the T9 transformer

should measure the polarization current.

The connection of units that polarize by V0 will vary upon

models, this voltage can be connected to T4, T5, T9 or

internally calculated.

PROTECTION FUNCTIONS


4/20

Sensitive neutral overcurrent (50/51SN)

Models with sensitive neutral unit are able to detect very

resistive earth faults. For sensitive neutral measurement, it isnecessary to use a toroid transformer connected to

transformer T5 or T4, depending on the model chosen.

If the model has directional overcurrent, the type of directio-

nal for this function can be chosen via setting:

angular watimetric I * cos f

I * sen f

Isolated neutral overcurrent (67IN)

The high sensitivity and the directionality of this function

allows detecting earth faults for isolated neutral systems

and very resistive earth faults. The isolated neutral current is

measured using the same transformer as that used for thesensitive neutral current measurement (see figure above).

Voltage controlled overcurrent (51V)

Lowers the pickup level of the overcurrent unit depending

on the voltage level. This reduces the tripping time in case

of severe faults (with voltage fall).

Cold Load Pickup

Avoids undesired trips produced by overcurrents at

connection time.

Tap changer lock (50TCL)

Enables an independent current level to be set which can

be used for various automatisms, such as tap changer lock,

to prevent the regulator from acting when the current is

enough to damage the tap changer.

Current unbalance (46)

Protects the installation against unbalances in current as a

result of anomalies in the power system or unbalanced

loads.

Broken conductor (46BC)

Detects when a phase of the installation comes down and

protects bays against this anomaly.

Breaker failure (50BF)

Detects failures in breaker actuation, providing information

to other protection units so that these accelerate their trip.

The PL-300 includes a three phase 50BF unit, and there are

models that include a single phase unit, monitoring each

phase separately

Overvoltage (59), undervoltage (27) and voltageunbalance (47)

There are models of PL-300 with the following voltage

functions: overvoltage, undervoltage and voltageunbalance, that can be independently enabled or disabled

according to customer needs.

Overvoltage function acts against voltage increases that

could endanger the isolation and security of the protected

units.

Undervoltage function protects, those loads connected to

the line, which are sensitive to line voltage drops.

Voltage unbalance function protects the installation against

the harmful effects of voltage unbalances, such as

excessive warming in motors, current unbalances, etc.

Zero sequence overvoltage (59N)

Protects against earth isolation failures in machines. Zero

sequence voltage can be obtained through an open delta

connection of the secondaries of three voltage transformers

(see polarization by V0 of 67N) or calculated as the vectorial

sum of the three phase simple voltages.

Thermal image (49)

Protect elements such as lines, transformers, etc, against

thermal overloads, calculating the temperature according tothe present and recent load conditions of the protected

device.

Fuse failure (68FF)

Detects if a fuse has blown up in the secondary circuit of the

voltage transformers. While detecting this situation,

functions 51V, 27 and 59N will remain locked.

5/20

Frequency unit (81 O, U, R)

Frequency units protect the Power System against loss of

balance between generated and demanded power.

There are models of PL-300 with the following frequency

functions: overfrequency and/or underfrequency and

frequency rate of change, that can be enabled or disabled

independently via setting according to customer needs.

There are 5 steps of frequency that can be programmed

independently as overfrequency or underfrequency,

allowing an underfrequency load shedding.

The frequency rate of change unit has 4 steps, this allows

the disconnection of loads before reaching undesiredfrequency levels.

Power protection (32)

There are models of PL-300 with the following power

functions, that can be independently enabled or disabled

via setting according to customer needs:

Minimum active and apparent power (independent) Maximum active and apparent power (independent) Reverse power

The maximum and minimum power (active and apparent)

units protect against excessive increases and decreases ofthe generated power.

The reverse power protection acts against motorization of

the generator.

Zones and pilot protection (85)

There are models of PL-300 that communicating with other

terminals allow the next pilot protection schemes: Permissive overreach

Permissive underreach Directional locking Directional unlocking

Additional schemes: ECO

Inverse direction locking

To carry out these schemes, the instantaneous units of 67

and 67N have 3 zones with independent settings for each

zone. The direction of zones 1 and 2 is forwards and the

zone 3 can be forwards or backwards.

Breaker monitoring (74TC/CC)

Breaker supervision by pole. Statistic of number of

breaker manoeuvres and breaker health monitoring bySkI2 counter

Possibility of supervision of 4 coils

Protection functions locking feature

Each of the protection functions can be locked by a digital

input or logic function (see programmable logic).

Syncrocheck (25)

It is used to supervise the closing of a breaker with voltage

on both sides. The function enables the closing when theangle, frequency and magnitude in both sides comply with

the set conditions. Synchrocheck function is made by

comparing voltages of phase B in both sides of the breaker.

The measurement of T7 is used against measurement of T9

or T5 connected to phase B of the other side of the

breaker:

Recloser (79)

PL-300 units include a three-phase recloser and by

actuation of the underfrequency unit (for models with 81Uunit) which gives a reclosure possibility for each step of the

81U unit.

The recloser also includes the option to enable the

sequence coordination function. Such sequence

coordination is applied when a number of units is installed

downstream and have a slow trip programmed with the last

reclosure. This function avoids the fast trip of the units that

are in a higher level, during the fast trip of the units that are

in the lower side.

High Current Lockout (HCL)

Provides a second instantaneous overcurrent unit at a

higher setting, so that its actuation does not produce

automatic reclosing.

AUTOMATISMS

5


6/20

Programmable logic

The user can configure up to 15 logic signals, that can be

assigned to output relays, LEDs, or inputs for protectionfunctions blocking features.

Logic selectivity functions

Logic selectivity functions that lockout the trip, but not the

pick-up of the instantaneous overcurrent and isolated neu-

tral directional units, can be done.

Special automatisms

The unit is provided by the following special automatisms:

Slack springs automatism: the unit watches the status ofan input assigned as "slack springs". If this input is

active during a time longer than the one programmed in

setting "spring slack time" the output "open spring

motor" is generated, this input is used to trip the switch

of the spring tightening motor's power supply Voltage presence: The automatism watches if the

average compound voltage is within particular values

and gives a control signal. When the average compound

voltage exceeds the presence threshold, the bit for the

control word is set to 1, and if it falls below the absence

threshold, that bit is set to 0

Close locking: If the circuit breaker is seen as closed, no

closing order is allowed from digital input, command,pushbutton or recloser

Open locking: If the circuit breaker is seen as open, no

opening order is allowed from digital input, command or

pushbutton

Measurements

The unit measures the following network parameters: Current for each phase (I) Neutral current (I)

Phase to ground voltage in each phase (kV) Average phase to ground voltage (kV) Phase to phase voltage for each two phases (kV)
