The Effect of Installation of Static Var Compensator (SVC) on 20 KV Distribution Network Power Flow

Introduction

The distribution of electric power from the plant source to the load center is a complex process that requires careful management to ensure the reliability and efficiency of the electrical system. In the 20 kV distribution network PM 6 in Pematangsiantar Substation, the quality of power and stability of the voltage on the end of the receiver are critical factors in maintaining the reliability of the electrical system. To achieve this goal, it is essential to manage power flow, voltage profile, and power losses that may occur during distribution. In this context, the installation of Static Var Compensator (SVC) has emerged as an important solution in increasing the efficiency of the distribution network.

The Role of SVC in Power Distribution

SVC is a type of power electronic device that is used to compensate for reactive power in the distribution network. By injecting or absorbing reactive power, SVC can help to stabilize the voltage at the end of the network, reduce power losses, and improve the overall efficiency of the distribution system. In the context of the 20 kV distribution network PM 6 in Pematangsiantar Substation, the installation of SVC has been shown to have a significant impact on the power flow and voltage profile.

Case Study: PM 6 GI Pematangsiantar

A case study was conducted to analyze the effect of SVC installation on the 20 kV distribution network PM 6 in Pematangsiantar Substation. The results of the analysis showed that the installation of SVC can increase active power up to 1.09 MW when the distribution generator (DG) operates, and suppress reactive power up to 6.239 MVAR. When the DG does not operate, the active power that was successfully increased reached 3,327 MW, with a reactive power depressed up to 7,176 MVAR.

Benefits of SVC Installation

The installation of SVC brings several benefits to the electricity distribution system, including:

  • Reduction of Network Losses: SVC can reduce losses by up to 44.54% of a total of 2,445 KW when the two DGs operate.
  • Improvement of Power Quality: SVC can help to stabilize the voltage at the end of the network, reducing the risk of disruption that can cause power outages.
  • Reinforcement of Reliability: SVC can improve the overall efficiency of the distribution system, making it more reliable and efficient.

Conclusion

The installation of SVC is a strategic investment for the development of better electricity infrastructure in the future. With the right analysis, SVC can be planned and implemented effectively to achieve optimal power management objectives. Along with the increase in energy needs, solutions such as SVC must be optimized to be able to support the reliability and efficiency of the electricity system throughout the world, including in Indonesia.

Recommendations

Based on the results of the case study, the following recommendations are made:

  • Further Research: Further research is needed to analyze the effect of SVC installation on other distribution networks.
  • Implementation of SVC: The implementation of SVC should be considered as a strategic investment for the development of better electricity infrastructure in the future.
  • Optimization of SVC: The optimization of SVC should be done to achieve optimal power management objectives.

Future Directions

The use of SVC technology is a relevant solution for the development of better electricity infrastructure in the future. As the energy needs continue to increase, solutions such as SVC must be optimized to be able to support the reliability and efficiency of the electricity system throughout the world, including in Indonesia.
