Hi,
I am trying to write a user written generator model of an energy storage in PSS/E 34.2, but I’m having trouble implementing it in FORTRAN. The model is not doing what it is suppose to do. I’m missing something in my model file. Does anybody have a sample user written generator model in PSS/E...
Hello Folks,
Can somebody explain me the space vectors theory used in field orientation control of IM. How space vectors are obtained and how space vectors are different from space phasors?
Thanks
Hello Folks,
I am new to the field of power system protection. I am working on a project where I have to calculate the values of 'Negative sequence directional element' for a radial system. I've successfully calculated the values of various parameters like pick up current, forward and reverse...
Hello Folks,
I am working on a project where I have to conduct protection and coordination studies of a loop system. Does anybody know how to select the zones of protection for a loop(mesh) system?
Thanks
Hello folks,
I am working on protection of a loop system, the system figure is attached. In this loop system, each section has two pilot protection relays. I've already achieved the protection of the system by using directional over current relay. Now in case of fault in any of the section we...
I have 3CTs which are passing current signals to SEL351S relay. When I am measuring the current phasors in relay they are showing following values:
A B C N G
I MAG (A) 6.604 6.734 7.331 0.000 13.759
I ANG (DEG) 174.51...
Hello Folks,
I want to know how positive directional element(F32P) is used to determine the direction of the fault current in SEL351S relay.
I have a system where I have to develop a PSCAD model to determine the direction of all possible kind of fault in loop. I have successfully implemented...
Hi folks
I am working on a short project to determine the detection of symmetrical fault occurence in loop system. Does anybody have a idea about this thing?
Thanks
Hello folks
Can anybody give me good idea of negative sequence directional element in power system protection? and How to set the relays by calculating the parameters of network.
Thanks
Hello guys,
I am working on distribution system where I have to develop a recloser control model in PSCAD. Although I have basic knowledge of recloser system but I couldnt find the control and operation of recloser system which I can emulate in PSCAD.
Any suggestions would be helpful to me.
I am currently working on solid state transformer protection system design. I have to design dc protection of 400 Volt dc link but constraint is that I can not use circuit breaker for protection as DC circuit breaker is expensive. Any ideas and suggestions are welcome
