Hi 7anoter4 (Electrical)
I haven't used this kind of application before. So, you are saying if I include an Is limiter as shown on slide 16 of 27 in the switchgear panel, then it will clear the fault within 5-10ms? This Is limiter will take the responsibility to clear the current fault by...
I have a new project on the technical review stage. Basically, this project has a single turbine generator is running a parallel with grid. But, the grid owner requested to clear a generator fault with 1/4 of cycle if there is a fault. If we could not do this, then the project is dead. So...
The former engineer who programed this AVR had chosen the following for mode of operation on DECS 200. It is working fine before until two days ago.
For Control Mode, he selected AVR. For Operating Status, he chose Off which means the DECS is not working in PF or VAR mode.
I asked this issue...
catserveng (Electrical),
Yes, I read this DECS manual. But, it didn't help me to resolve the issue I had. Do you understand the LOSS OF FIELD LEVEL set point on this DECS 200? What does it do?
Mike, yes we are using Bestcoms software to do the set points. This is a new technical issue with an existing site. We didn't have this problem before.
Basically, the customer had this problem synchronized with grid after the grid came back from a failure. This is only once in awhile issue...
Yes, I had the pf set point of 0.8. Before the turbine generator is synchronzing with grid, the DECS 200 displayed -0.26. Right after generator is paralled with grid, the DECS 200 displayed 0.86. But then the pf kept decreasing to become a negative number of -0.98.
Can somebody explain to me...
I decided to increase the loss of field value from 450 to 750kvar on the DECS 200. The turbine generator was able to synchronize with the utility for now. However, I read the multimeter on the turbine generator side, it gave me a power factor of -0.971 with a Kvar of -0.350 Mvar. Would...
I tried to synchronize the turbine generator with Utility. But, after 30 seconds of synchronizing with utility. I got an alarm and it opened the turbine generator's breaker. I went to check the DECS 200, it displayed a message Loss of Field Excitation.
It happened like this three times now...
This project will be a baseload application. Are there any other electrical devices require for this kind of application? Do we have to do any kind of modification on our turbine side?
My company's specialty is packaging Turbine with synchronous generator as a finished packaging for baseload or standby application. We have a new customer asking for an Induction generator instead. My understanding of Induction generator requires utility power to provide exciting to this...
We don't have a manual synchronizing operation. Our customer only wants automatic synchronzing operation.
The Woodward SPM auto synchronizer part nunmber is 9907-028
I have talked to Woodward technical support, he said this model has without voltage matching, so it only looks for phases of...
We have a baseload gas turbine generator system. We have a Basler DECS-200 as a voltage regulator, Woodward SPM as an Auto-synchronizer, and Woodward Load Sharing Module. The utility voltage is rated at 13.8KV. As long as the utility voltage is dropping down to 13.4kv or more, the gas turbine...
