hello dear all ! We have a power plant with three Gas Turbines (Frame V GE model with Mark-VIe control) running in synchronism with national power grid. Based on the plant process load out plant runs either in power export or import mode. All the GTs are running in droop mode with LCM (load...

Hello all, With due regards to this esteemed forum I want to have a silly information which is related to Occupational health. I have been working in Gas Turbine based CPP ( beginner) where noise is a big issue, around 90db in the GT hall itself and to get rid from the noise issue , I want to...

Hello all ! In one of gas turbines (frame-V, 19.6 MW with mark-VIe control system) of our co-generation plant (with three gas turbines), today we have observed sudden change in lube oil header temperature from 64 deg C to 71 deg C, when the GT was running at a load of 19 MW. Other two gas...

Hello all ! Kindly share some information on Rotor earthing Brush of Gas turbine (GE make Frame-V, 20MW with Mark-VIe control system). (1) What is its function (2) What will happen it the carbon brush gets completely depleted while running due to wear & tear. (3) what kind of alarm we are...

Hello everyone, Myself into operation & maintenance of a small power plant (60 MW with 3 nos frame-V Gas turbine with Mark-VIe control and our plant always synchronized with national grid). Now in a project of new Gas turbine (again frame -V @ 20 MW), we are being supplied a system of...

Hello everyone,, Myself into operation of a co-generation plant with three GE make frame 5 gas turbines with capacity@20MW with Mark-VIe control system. In the generator control panel we have Beckwith make generator protection relay (model:M-3425A) and the DAVR is of Brush make (Make: BRUSH...

Hello everyone, Myself working in a co-generation plant with 60 MW(3x20MW) generation with three gas turbines with HRSG boilers. I want to learn about the starting engine (diesel engine) functioning like how it helps to get the gas turbine to its self sustaining speed. In this effort I have...

Hello everyone! I have recently joined operation of an gas turbine power plant in india. GE make gas turbines are installed here (19.6 MW) with mark-VIe control system. I could acquire a drawing of "scheme for control devices", which is of course of a new project being underway. I need help to...

Hello everyone, In one of our LSTK project of Gas Turbine, 15MW,BHEL (bharat heavy electricals Ltd) make turbine & generator with Mark-VIe control, the contractor has supplied the Turbine and the generator separately, and waiting for the foundation/skid to be ready in install both. But...

Hello everyone, We are in operation of 19.6 MW GE make gas turbine (Mark Vie control system) with Brush make alternators. There are nine RTDs installed for alternator i.e. : 1. Stator coupling end : 3 nos, (DTGSF1, DTGSF2, DTGSF3) 2. Stator collector end : 3 nos : (DTGSA4, DTGSA5...

Hello everyone, please throw some light on this. When we give a start command to a gas turbine (say GE make, 19.6 MW, Frame-5, Mark-VIe control with prime mover is diesel engine), what are the steps through which it reaches FSNL (full speed no load). i.e., Functional description of starting...

Hell everyone, Myself engage in operation of GE make gas turbine generator (19.6 MW, Frame-5, Mark-VIe control). kindly explain the fire protection system of the turbine-generators. As per the schematic, there are UV detectors & thermal detectors in aux compartment, turbine compartment, L/G...

Hello everyone... I am working on gas turbine operation (19.6 MW, frame-V, GE make turbine, Brush make Alternator). I would like to know what are the MINIMUM turbine parameters which are to be monitored by us to keep our turbine healthy (log sheet is too huge to monitor) along with its set...

Hello everyone.... I am working in operation of Gas turbine (19.6 MW, Frame-5 with Mark-VIe). My query on staring logic of auxiliary motors was explained in this forum (Thanks CSA..) Can anyone help me also to make out how the auxiliary motors (AOP & EOP) get the start command and also...

Hello everyone, I am working in a captive power plant having GE make gas turbine @19.6 MW capacity (frame-V) with Mark-VIe control system. Kindly help me understanding the logic of starting of auxiliary motors like (i) Aux Lube oil pump motor, (ii) emergency lube oil pump motor, (iii)...
