Speedtronic Mark V
Speedtronic Mark V by general electronic is one of their most productive creations yet. This gas turbine control system is a bestseller for the company and utilizes DS200LDCCH1A as its exciter board. The Mark V holds a triple-redundant 16-bit microprocessor controller. The control system’s software-implement Fault Tolerance includes 2/3 voting redundancy with critical control parameters for protection. Accordingly, The Mark V is an operator’s first choice regarding reliability lower force outages.
To understand the working of DS200LDCCH1A better, you need to comprehend the working of exciter boards.
Exciter boards
Exciter boards are a critical part of an excitation system. This system provides the rotor winding of a generator with a field current. Therefore, an excitation card is a vital component of the board. In addition, a well-design card like DS200LDCCH1A can provide reliability, fast transitory response, and excellent stability. An exciter board uses an Automatic Voltage Regulator to supply Direct Current output to the exciter state.
DS200LDCCH1A salient features
DS200LDCCH1A has an instant reset function for software and hardware. It also has Local Area Network control via a microprocessor along with Communication for driving input/output through LAN. Additionally, some other features include:
- Processing of drive, customer input/output functions, and motor through microprocessor control.
- Software adjustments and diagnostic testing through the operator interface.
DS200LDCCH1A compatibility
This exciter chip has made its mark on the Speedtronic series over time. Subsequently, it has become a go-to for use in the Mark V gas turbine control system. Although, A big chunk of credit for this dependability goes to the system’s reliability provid by the SIFT feature. The Mark V control system is a perfect match for gas turbine controls. Moreover, this is because they fulfill all the standards of gas turbine control. Mark V takes the help of a digital microprocessor to modulate the entire operations of a gas turbine.
DS200LDCCH1A Microprocessors
There are four central processors in the DS200LDCCH1A exciter card.
Motor control processor
Motor control processors are controll remotely, manually, or automatically. The primary purpose is to start or stop the motor fasten to the machine. Therefore giving control for motor control circuits and input/output communications. Usually, C2000 microcontroller processors are brought into use to control a wide array of applications. The location of this processor is U21.
Drive control processor
The drive control processor is the controlling circuit that allows the Communication between a hard drive and the central processing unit of the exciter board. In addition, it establishes control for integrate peripheral Input/output like timers and decoders. The location of this processor is U1 on the LAN COMM board.
LAN control processor
The LAN control processor works on the’ five bus system’ having two generators at G1 and G2 whereas three load buses at 3, 4 and 5 along seven transmission lines. This processor is in position U18.
Co-motor processor
This processor is for assisting the motor control processors when a calculation gets too complex. A co-motor processor will provide the extra processing power to complete the task at hand. This processor is in the U35 location.
Manual to follow for DS200LDCCH1A installation
When working with DS200LDCCH1A, it is best to apply the GE Motors, and Industrial Systems Drive Control/LAN Communications Board Manual. Another way to refer to this manual is GEI-100216. Although this manual covers specifics of DS200LDCCG1A drives, it does cover the basics of LAN Drive Control Communications Boards.
Installation briefing
First off, use the bayonet connectors to connect the board to committees and various devices across the drive. There are two fundamental parts to the connector: male and female receptors. Before joining these two receptors, there are certain things you need to keep in mind. Before removing the bayonet, firmly hold the connecting receptor with one hand while holding the board with the other hand. It is crucial to make sure there is no bending or shifting. Make sure to keep it in mind upon removal of bayonet connection from the female receptor. Till you are ready to attach the connector to a new board, ensure that the cables are set aside.
Precautionary measures
One critical thing to remember is that bayonets are to be handle with care. There should be no tugging or hauling on them to separate them. Instead, hold the connector gently and slightly twist and pull them. Hence, never pull on the cables. It is because the sudden heave can damage the line.
Furthermore, ensure that no other board component gets in contact with the bayonet connection. It increases the risk of bending or scuffing the board’s surface details.
Intervention
The exciter board comprises a total of 30 jumpers, two bayonet connectors, and three fuses in its components. Upon removal of the circuit breaker, the berg jumper must be reset. It is also vital to keep the operating instructions of the microprocessor in check as it is store in programmable read-only memory modules.
