Transmission and Substation Management

Good Management of transmission and substation have five parts: 

1. Preparation Businesses  
Before the given voltage substation and bears (on the operation of the new substation is completed in the wake) than previously stated by the maintenance team (which is installing and testing) that the substation is ready to operate. All equipment (power transformers, breakers, the source of direct current and so are qualified to operate. Does relay settings are in accordance with prescribed, firefighting equipment, are already eligible, the work equipment does not interfere with the operation and was kept in place. After that report is ready for operation. 

2. Supervision and Examination  
Careful supervision at the location of substations that are running is to prevent interference with power distribution and damage to equipment, among others: • Control of interference of external factors Disorders that arise are caused by humans, animals, plants and others. • Supervision factors disturbance inside. Disorders that arise are caused by factors within the existing equipment at the substation. • communication systems, direct-current source system, fire extinguishing system must always be good in every operation. 

3. How to turn off or Free Voltage at substation  
How to turn off and relieve stress on the sub station is as follows: that is, remove all load breakers, cables, and then dividing and then enter the soil separator of each breaker that has been removed, remove the power transformer, remove the breaker Conductor later separation. When the Conductor is no voltage divider again enter the land (if necessary). 

4. Concession Boundary 
Regarding the limits of exploitation of the equipment to look at the manual operation, exercise and maintenance of equipment.

Duties and Responsibilities of Workers in The Transmission and Substation

The duties and responsibilities of workers in the transmission and substation are:

 1. Operation
Plan activities based on the guidance or coordination with the AFL / related functions, dividing the tasks and giving instructions to his subordinates, and check the performance of the equipment, the operation to ensure reliable operation of substations and substation circuit.
 
2. Maintenance
Develop action plans, coordinating with the AFL / related functions, divide tasks, provide guidance and oversee the maintenance work of transmission and substation and substation circuit, record and report on the implementation of maintenance to support the reliability of electric power distribution system.
 
3. Administration
Develop action plans, coordinating with the AFL / function related, sharing tasks, giving instructions to subordinates as well as serve the material needs for operations and maintenance and carry out general administration, personnel, finance and secretariat based on the guidelines and instructions in force to support the operation and maintenance of transmission.
 
4. Transmission and substation technicians
Carry out maintenance, repairs substation equipment, substation and transmission circuit in accordance with the guidelines and guidance of maintenance and repair

Electric Power Distribution Process

Voltage generated from the gas turbine generator and steam turbine generator is still low so the voltage should be sent in advance to the main transformer 11.5 / 150 KV to increased tension. 150 KV voltage generated from the main transformer 11.5 / 150 KV transmission subsequently flowed through the poles in the switch yard and then sent to the substation through a transmission voltage and extra high voltage.

Production Process Steam Turbine Power (power plant)

Secondhand gas out of gas turbines used again after the first set by the regulator valve (selector valve) to flow into the boiler / HRSG to vaporize water from water storage drums. The resulting steam used to turn steam turbines coupled with generators that can generate electricity. Steam turbines used from condensed steam again in the condenser, then the result of condensation water in the pump by Condensate Pump, then fed back into the deaerator and the feed water pump is pumped back into the drum for re-evaporated. This is called the Cycle Closed / closed cycle. So in brief it can be said that the Closed Cycle / closed cycle is a series of Open Cycle coupled with the process of recovery of exhaust gas from Open Cycle process to produce steam to drive a steam turbine.

Process Power Plant / Gas Turbine Power Production

In the process of Gas Turbine Power Production, cranking motor is used as an early player when the turbine is not producing power by using the electrical energy drawn from the power grid 150 kV / 500 kV. Cranking motor serves as a vacuum compressor air play outside, with the first through the Air Filter. Outside air will be converted.

Electricity Production Process Gas Power Plants

 In general, electric power production system on gas power plants is divided into two cycles, there are: 

Open Cycle  
Open Cycle is the process of electricity production in power plant where the exhaust gases from gas turbines directly discharged into the air through the chimney channel output. The temperature of exhaust gases in the flue channel of this output is 550 C. Such a process is in the Central Power Plant Steam Gas (gas power plants) may be cited as the Power / Gas Turbine Power Production (gas power plants) is a process of generating electricity generated by gas turbine cycle. 

Closed Cycle
If the Open Cycle Gas turbine exhaust gas from directly discharged through the chimney channel output, then in the process of Closed Cycle / closed cycle, the flue gas from a gas turbine will be used prior to cooking water in the HRSG (Heat Recovery Steam Generator). Then the steam generated from the HRSG will be used to turn steam turbines to generate electricity after the first turn the generator. So the cycle of Closed / closed cycle is called as the Power / Gas Power Production Steam (gas power plants) is the process of electricity generation produced by the rotation of gas turbine and steam turbine. 

Power Plant

The rapid development of technology is a major factor in influencing the progress of the industrial world. All the necessities of life are in need of clothing, food, shelter and all forms of goods - luxury goods industry is a result that is not out of touch technology applied in industry. In various parts of the world there are a variety of industries from the national level to international level. Similarly, in our country, various industries have been established and well developed that aims in terms of satisfying the needs of the community life of Indonesia.
