Welcome to my channel PSP-Protect.
2
Today we will see how to configure control inputs in Mycom relays.
3
We are having P642 relay and today we will design basically two logic.
4
One is to take the under frequency element tripping output and another is the breaker control.
5
For breaker control we will use control input 1 and 2,
6
1 for on and 2 for off
7
and control input 3 will be used to determine whether to enable or disable the tripping output of under frequency relay.
8
In order to use control input in mycom relays we need to configure three things the setting files the PSL
9
and MCL file.
10
In this setting file,
11
first of all we will change the control input configuration where we will change control input 1 as pulse,
12
control input 2 as pulse and both of them will be used for breaker control.
13
third control input will be used for under frequency element enabling
14
and disabling so
15
that will be latched now you can get three options set
16
reset on off enable disable in this control input function it
17
can be pulsed as well as latched now pulsed are used for
18
breaker control and latched will be used for other purposes where we need a latching property
19
we need to move on to relay output so in case of output we have to configure two things one is
20
relay output 2 and relay output 3
21
which will be used for breaker control now we will use relay output 3 for CB on
22
and relay output 2 for CB off these outputs will actually give the actuating commands to the circuit breakers
23
now you can see that for control input 1
24
and 2 we have used the pulsed command
25
and for control input 3 we have used enabled and disabled command
26
because it will be latched either in enabled condition
27
or in disabled condition but for breakers it should be pulsed
28
because continuous output should not be given to the breakers or isolators where there are actuating coils
29
now we are labeling the control input names because this will be displayed on on the screen of the concerned relay.
30
So there will be three names will be displayed one for circuit breaker on circuit breaker off
31
and the third for under frequency enable or disable so for that we need to give the names in control input levels
32
now we will save this and we will move on to the PSL section in the PSL section
33
we have to we have we need to design the things which which you will see now
34
first of all we will go to the under frequency enable
35
or disable function so for
36
that we need to make the under frequency element free from the tripping output
37
and we will use an AND gate with the control input 3
38
and then we will connect the output to the tripping command
39
so in the earlier what was there is
40
that as the under frequency element gets actuated it will give tripping output
41
but now we have made a control input 3 in we have made the control input 3 and
42
under frequency through an AND gate so that
43
when both of them will become high that is under frequency element has operated
44
and we have enabled the control input 3 then only it
45
will give the tripping output otherwise the under frequency element will become high
46
but no tripping output will be given through the trip relay
47
so this is connected to the any trip through this
48
and gate so that when both of the signals will be high then only it will give the tripping
49
otherwise only under frequency output will be given as annunciation
50
so next we will move on to configure the circuit breaker operation for
51
that we need two of the relay outputs
52
which will be used for to give command to the circuit breaker one is CB1
53
and CB2 CB on and CB off that is really one a relate to
54
and relate three and we need two control inputs control input one a control input 1 and control input 2
55
so we will simply connect this control input 1 to CB on and control input 2 to CB off
56
and to show actually the circuit breaker CB status should
57
be given through the opto input as it is given in
58
the PSL you can see in LED number eight for CB status
59
Now the next part of the configuration is the MCL file.
60
In MCL file also we need to configure the control input segment.
61
Others we will see
62
or we will cover later on in the later videos where
63
we will use the GUZ operation where we will see the GUZ operation
64
but now in this video we will basically focus on configuring the control input
65
so first of all in the communication you can see the IP address is given
66
which will be basically used for GUZ and in sntp segment also we have
67
given the we need to give
68
the IP for SNTP communication
69
or to give the time stamping to each
70
and every event in the relay so
71
that will be given in this SNTP segment whichever clock
72
or whichever GPS system is connected to the system through Ethernet port we need to give the address of that SNTP server
73
in this SNTP segment now other things like data set goose
74
publishing goose subscribing we will do it later now in the
75
control input the control segment we need
76
to move on to SPC SPCS segments in
77
the SPC segment there will be 32 spcs which are for control inputs
78
you can see this spcs 0 spcs 0 1 0 2
79
0 3 like this there are 32 inputs now we have used only three control inputs
80
so in this three we will change the CTL mode from
81
status only to direct with normal security then only they will operate
82
so change it to direct with normal security
83
or direct with enhanced security anything but if they are kept in the status only mode then they will
84
not operate so for first three SP CS 0 1 0 2 SP CS 0 1 0 2
85
and 0 3 we have changed it to direct with normal security this is the only change
86
which we need to do in the MCL file
87
Thank you.
88
Now, another
89
small change we need to make in the setting segment
90
that is the hotkey configuration there is a button in the relays mycom relays called hotkey where under
91
which we can select how many control input we want in the screen
92
now we have to once again move on to the PSL segment because as I was saying that for the
93
feedback of the CV status we need to take an opto feedback
94
or opto output a opto input to show what is the status of the CV
95
but through an LED as it is already configured here in in LED number 8
96
but here the relay is not connected to the breaker.
97
So already here we have again configured LED number 4 for under frequency to show it.
98
In a similar way LED number 8 will be used to show
99
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

쉐도잉이란? 영어 실력을 빠르게 키우는 과학적 방법
쉐도잉(Shadowing)은 원래 전문 통역사 훈련을 위해 개발된 언어 학습 기법으로, 다언어 학자인 Dr. Alexander Arguelles에 의해 대중화된 방법입니다. 핵심 원리는 간단하지만 매우 강력합니다: 원어민의 영어를 들으면서 1~2초의 짧은 지연으로 즉시 소리 내어 따라 말하는 것——마치 '그림자(shadow)'처럼 화자를 따라가는 것입니다. 문법 공부나 수동적인 청취와 달리, 쉐도잉은 뇌와 입 근육이 동시에 실시간으로 영어를 처리하고 재현하도록 훈련합니다. 연구에 따르면 이 방법은 발음 정확도, 억양, 리듬, 연음, 청취력, 말하기 유창성을 크게 향상시킵니다. IELTS 스피킹 준비와 자연스러운 영어 소통을 원하는 분들에게 특히 효과적입니다.
