Welcome to my channel PSP-Protect.

Today we will see how to configure control inputs in Mycom relays.

We are having P642 relay and today we will design basically two logic.

One is to take the under frequency element tripping output and another is the breaker control.

For breaker control we will use control input 1 and 2,

1 for on and 2 for off

and control input 3 will be used to determine whether to enable or disable the tripping output of under frequency relay.

In order to use control input in mycom relays we need to configure three things the setting files the PSL

and MCL file.

In this setting file,

first of all we will change the control input configuration where we will change control input 1 as pulse,

control input 2 as pulse and both of them will be used for breaker control.

third control input will be used for under frequency element enabling

and disabling so

that will be latched now you can get three options set

reset on off enable disable in this control input function it

can be pulsed as well as latched now pulsed are used for

breaker control and latched will be used for other purposes where we need a latching property

we need to move on to relay output so in case of output we have to configure two things one is

relay output 2 and relay output 3

which will be used for breaker control now we will use relay output 3 for CB on

and relay output 2 for CB off these outputs will actually give the actuating commands to the circuit breakers

now you can see that for control input 1

and 2 we have used the pulsed command

and for control input 3 we have used enabled and disabled command

because it will be latched either in enabled condition

or in disabled condition but for breakers it should be pulsed

because continuous output should not be given to the breakers or isolators where there are actuating coils

now we are labeling the control input names because this will be displayed on on the screen of the concerned relay.

So there will be three names will be displayed one for circuit breaker on circuit breaker off

and the third for under frequency enable or disable so for that we need to give the names in control input levels

now we will save this and we will move on to the PSL section in the PSL section

we have to we have we need to design the things which which you will see now

first of all we will go to the under frequency enable

or disable function so for

that we need to make the under frequency element free from the tripping output

and we will use an AND gate with the control input 3

and then we will connect the output to the tripping command

so in the earlier what was there is

that as the under frequency element gets actuated it will give tripping output

but now we have made a control input 3 in we have made the control input 3 and

under frequency through an AND gate so that

when both of them will become high that is under frequency element has operated

and we have enabled the control input 3 then only it

will give the tripping output otherwise the under frequency element will become high

but no tripping output will be given through the trip relay

so this is connected to the any trip through this

and gate so that when both of the signals will be high then only it will give the tripping

otherwise only under frequency output will be given as annunciation

so next we will move on to configure the circuit breaker operation for

that we need two of the relay outputs

which will be used for to give command to the circuit breaker one is CB1

and CB2 CB on and CB off that is really one a relate to

and relate three and we need two control inputs control input one a control input 1 and control input 2

so we will simply connect this control input 1 to CB on and control input 2 to CB off

and to show actually the circuit breaker CB status should

be given through the opto input as it is given in

the PSL you can see in LED number eight for CB status

Now the next part of the configuration is the MCL file.

In MCL file also we need to configure the control input segment.

Others we will see

or we will cover later on in the later videos where

we will use the GUZ operation where we will see the GUZ operation

but now in this video we will basically focus on configuring the control input

so first of all in the communication you can see the IP address is given

which will be basically used for GUZ and in sntp segment also we have

given the we need to give

the IP for SNTP communication

or to give the time stamping to each

and every event in the relay so

that will be given in this SNTP segment whichever clock

or whichever GPS system is connected to the system through Ethernet port we need to give the address of that SNTP server

in this SNTP segment now other things like data set goose

publishing goose subscribing we will do it later now in the

control input the control segment we need

to move on to SPC SPCS segments in

the SPC segment there will be 32 spcs which are for control inputs

you can see this spcs 0 spcs 0 1 0 2

0 3 like this there are 32 inputs now we have used only three control inputs

so in this three we will change the CTL mode from

status only to direct with normal security then only they will operate

so change it to direct with normal security

or direct with enhanced security anything but if they are kept in the status only mode then they will

not operate so for first three SP CS 0 1 0 2 SP CS 0 1 0 2

and 0 3 we have changed it to direct with normal security this is the only change

which we need to do in the MCL file

Thank you.

Now, another

small change we need to make in the setting segment

that is the hotkey configuration there is a button in the relays mycom relays called hotkey where under

which we can select how many control input we want in the screen

now we have to once again move on to the PSL segment because as I was saying that for the

feedback of the CV status we need to take an opto feedback

or opto output a opto input to show what is the status of the CV

but through an LED as it is already configured here in in LED number 8

but here the relay is not connected to the breaker.

So already here we have again configured LED number 4 for under frequency to show it.

In a similar way LED number 8 will be used to show

that this CB on and off operation is taking place through relay or not.

100

For that we will make a small change.

101

is LED number 8 will be connected as the breaker is on

102

when we give the command to CB on control input then this CB on output will be high along with

103

that we will give a latching command to LED number 8

104

which will show that the CB on pulse has gone to gone through the output number 3.

105

Now, CB OFF pulse will go to output number 2 to show that we have used a latch reset function,

106

we have used a latch reset function

107

which will make the LED of the relay we will reset the LED of the relay

108

so when we push the control input 1 to make the CB on the LED will glow

109

and as we push the CB off the LED will become off through the latch reset function

110

so in this way we will show how the breaker will operate in normal cases

111

but this is just to show you how it can operate as you can see

112

that there is a hotkey button

113

so otherwise the relay is not connected to any line

114

or feeder

115

so as we push the hotkey you can get the hotkey

116

menu in the hotkey menu we have setting group selection we

117

can select now you can see the circuit breaker on off

118

and under frequency functions are there as we have enabled them

119

in the hotkey now as I push the on you can see the LED number 8 is glowing

120

because the ON command is

121

given to the LED now as I push the OFF the

122

LED has reset now in the under frequency also as I

123

have pushed enabled LED number 4 is glowing as I push the disable again it will go off

124

so in this way we can use the control inputs in

125

various way in different logic in different relays of my phone thanks for watching my video

Что такое техника Shadowing?

Shadowing — это научно обоснованная техника изучения языка, изначально разработанная для подготовки профессиональных переводчиков и популяризированная полиглотом доктором Александром Аргуэльесом. Метод прост, но эффективен: вы слушаете аудио на английском от носителей языка и немедленно повторяете вслух — как тень, следующая за говорящим с задержкой в 1–2 секунды. В отличие от пассивного прослушивания или грамматических упражнений, Shadowing заставляет мозг и мышцы рта одновременно обрабатывать и воспроизводить реальные речевые паттерны. Исследования показывают, что это значительно улучшает точность произношения, интонацию, ритм, связную речь, понимание на слух и беглость речи — что делает его одним из самых эффективных методов для подготовки к IELTS Speaking и реального общения на английском.
