Perancangan Sistem Kontrol Glycol Regeneration Unit dengan Dcs Deltav di Onshore Gas Plant

The glycol regeneration process is an integrated part of the glycol dehydration unit (GDU) system. Each plant has a customized configuration to the needs of the process, for the case in this onshore field because the gas produced from the well is good enough with a fairly low water content, then does not use Glycol Contactor. Instead used low temperature separator and glycol generation unit. DCS DeltaV is used to operate, documentation and optimization of gas processes. By using oscillation method and closed loop system obtained PID tuning result with parameter P = 387, I = 57 and D = 53. The response of the control system is conditioned overshoot from its setpoint to accelerate the rise of the temperature plant. When the temperature of glycol regeneration is at 2620 F, the alarm will light Hi limit and Hi Hi limit at 2900 F, while at 2450F the alarm will light low limit and Low Low limit at temperature 00 F

Penerapan Metode Graphic Rating Scale (Grs) dalam Penilaian Kinerja Karyawan

Competition increasingly competitive business trigger Muliadana company to be more innovative in improving the quality of the company. One technique used by management companies in improving the quality of human resources is to conduct employee performance appraisal. To the authors try to establish a scoring system using the Graphic Rating Scale (GRS), which is a methodology for assessing the scale of the graph by comparing the individual performance against an absolute standard. The purpose of this valuation method is to minimize the less objective assessment and can determine the development of the employee's performance over several periods. The results of the performance appraisal company can provide feedback to the employees so they can decide the steps taken in making decisions such as: promotion, promotion or class, mutation, degradation as well as training for employees in need

Analisa Pembangunan Saluran Transmisi 275 Kv antara Gi Kiliranjao dan Gi Payakumbuh

Electrical energy is very important role in human life. rapid population growth resulting in increased electricity needs in Indonesia. Based on the current state of power supply capacity of the next few years will not be able to meet the electricity demand in a number of regions in Indonesia. Therefore PLN as a provider of electrical energy as possible to meet those needs. One step is made by planning to build Transmission Line T / L 275 kV substation Kiliranjao - GI Payakumbuh. With the construction of the substation, it is also necessary distribution of electrical energy that is supplying power to a great everincreasing burden on the city through the transmission line (SUTET) 275 kV. In this study will discuss the environmental feasibility study of development of the transmission line T / L 275 kV Kiliranjao - Payakumbuh and substation. Environmental feasibility study is to obtain accurate information in anticipation of environmental problems that arise and will occur as a result of the construction of the transmission T / L 275 kV, which is useful for various parties, such as PT. PLN as the initiator, the Local Government and Communities

Analisa Proteksi Differensial pada Generator di Pltu Suralaya

Power plants produce electrical energy that will be distributed to consumers. Hence, the power plant is expected to be in a condition which means it can reliably provide electricity continuously with good quality. So as to improve the reliability and continuity of service, the operation of power systems require a safety equipment or protection system to prevent disturbances that disrupt the system. Protection system is an important component to maintain the continuity and reliability of the distribution of electrical energy. Protection system serves to protect equipment from damage in the event of disturbances and minimize disruptions from spreading. With good protection system, the unwanted loss can be avoided, especially in the vital equipment such as generators and transformers. One of the equipment that plays a role in the protection system is a differential protection relays are used to protect generators and transformers. This relay protects the generator and transformer from internal disturbances such short circuit between phases or short circuit of phase to ground. This rele works based on the current setting and operating time has been determined so that it can work quickly and precisely targeted
