GE Speedtronic Gas Turbine Control Systems

A gas turbine is an internal combustion engine comprising combustion chambers that releases expanding gases, which further drive the blades of a turbine. The gas turbine converts natural gas and other liquids into mechanical energy. This energy then fuels generators to produce electrical energy. The various advantages associated with gas turbines are high power to weight ratio and low operations pressure. Despite being small in size, the gas turbines possess a high power rating.

They reduce carbon emissions and release fewer emissions into the air as compared to other engines. Thus in coming years, the growth in the substitution of coal and nuclear-driven turbines is expected to create a significant demand for gas turbines. This increase is further anticipated to drive the gas turbine market. The gas turbine market in Europe is expected to grow US$ 6,625.6 Mn by 2027. It is estimated to grow at a CAGR of 3.2% from 2019 to 2027.

In the aviation industry, gas turbines propulsion systems are used to power almost all commercial and military airplanes. It is projected that in the next 20 years, more than 40,000 new aircraft with gas turbines will be produced. Gas turbines power the oil and gas industry all along the value chain.

What is a gas turbine, and how does it work?

A gas turbine is a type of power plant that uses a combustion engine to convert natural gas or other liquid fuels into mechanical energy. This energy is then used to power a generator, which generates the electrical energy that is ultimately distributed to homes and businesses via power lines.

• At hundreds of miles per hour, the compressor takes air into the engine, pressurizes it, and feeds it to the combustion chamber.
• The combustion system consists of a ring of fuel injectors that continuously feed fuel into combustion chambers, where it combines with the air.
• The mixture is heated to almost 2000 degrees Fahrenheit and then burnt. A high-temperature, high-pressure gas stream enters and expands through the turbine section as a result of the combustion.
• The turbine is made up of a complex system of stationary and spinning aerofoil blades. The rotating blades rotate as hot combustion gas expands through the turbine. The whirling blades have two jobs: they drive the compressor, which draws more pressured air into the combustion area, and they spin a generator, which generates energy.

What is GE Speedtronic?

The GE SPEEDTRONIC turbine control is the current state-of-the-art control for GE turbines with a proven track record of over 30 years of reliable service. You get the benefits of GE’s unrivaled knowledge with an innovative turbine control platform with Mark VI.

Why GE Speedtronic Control System?

The Speedtronic Gas Turbine Control System handles a variety of tasks, including fuel, air, and emissions control; turbine fuel and auxiliary sequencing for a startup, shutdown, and cooldown; generator and system synchronizations and voltage matching; and monitoring of all turbine control, and auxiliary functions.

What is Speedtronic TMR Control?

Modular in three ways A design with built-in redundancy is known as redundant control. The system has three microprocessor controllers (designated R>, S>, and T> in the case of the Mark IV). A C> communications microprocessor is also included. The system continues to function as long as two of the three agree.

What is Mark I & II Control?

Mark I

Mark I turbine control was introduced in 1960 s. GE Mark 1 control panels had an average of fifty PCBs (printed circuit boards) and three input loops, including a start-up, temperature, and speed loop.

I worked on a “redundancy by association” strategy with Mark I. This meant that when one control, such as temperature, was active, the system was backed up by the speed control. This provided process fail-safety to the system, though not to the same extent as subsequent, more advanced systems like the Mark IV.

Mark II

Solid-state integrated circuits and a new cabinet configuration were added to the GE Mark II, which improved on the Mark I. For the first time, the circuitry enabled the practical implementation of sophisticated functions such as combustion monitoring.

In both Mark I and Mark II, control was based on three loops (startup/speed/temperature), with the least fuel-consuming parameter taking precedence. This minimal value gate’s output was labeled as VCE (electronic control voltage.) The amount of fuel utilized was determined by this variable. The Mark I employed 28 VDC relays for sequencing. For sequencing, the MKII used digital logic software.

What is Mark IV control?

The Mark IV offered a new CRT operator interface that displayed the status of logic functions and values. The display made it easier for operators to modify values as needed. Which could be done from the panel rather than the old approach of manually adjusting values using a linked voltmeter after finding the relevant potentiometer on the corresponding board.

What is Mark V control?

The GE Mark V Control System is built to meet all of your gas turbine control needs. These include speed-dependent control of liquid, gas, or both fuels, load control under part-load situations, and temperature control under maximum capability conditions or during startup conditions.

What is GE Mark VI?
