What is Power System Study?
The power system study is made up of several electrical engineering analysis and investigations. Electric power system study or electrical studies is also a group of studies used to analyze a power systems response to events over different time periods. An electric power system is a network of electrical components deployed to supply, transfer, and use electric power. The ultimate goals of power system studies are to have a safe, efficient and reliable power systems for an electricity system or facility both under normal and abnormal conditions —Omazaki Engineering is a power consultant who serves power system studies consulting services and analysis using ETAP (Electrical Transient Analysis Program) software for electrical system design. If you are looking for electric power system consultant company to study and design your project or power systems facilities in Indonesia and South East Asia Contact Omazaki Engineering, with experiences certified power system engineers & consultants, by sending an email to cs@omazaki.co.id or filling in the form in contact.
The Time Periods
There are three over all time periods that a power system study will look at, they are:
- Transient
- Dynamic
- Static

Importance of Power System Studies
Electrical power system studies are a prerequisite for any new electrical system development, renovation, modernization and expansion plan. In addition, this study is also a step so that the existing system can meet the objectives of system planning, design, protection and control, developing a system operation strategy, commercial and evaluation and technical feasibility studies.
The electric power system consists of various subsystems which include generation, transmission and distribution.
Purpose of Power System Analysis or Electrical Study
The objectives of the power system analysis are as follows:
- To create a model or perform a power system component phase analysis
- To monitor voltages on different buses, real and reactive power flow between buses
- To plan for the future development of the current system
- To analyze systems under different fault conditions and based on different scenarios
- For designing protection devices, as well as for investigating the system’s ability to handle minor and major interruptions or any errors.

Why Do We Need Power Systems Study for Electrical Facility?
Facilities of all sizes from ordinary industrial, to skyscrapers, to large industrial or commercial facilities all rely on stable, reliable and well-maintained power systems. Even minor electrical disruptions can have devastating consequences such as long and costly downtime, damage to critical equipment or assets in the event of a power outage, and the costs of locating and repairing faulty electrical equipment itself.
There are various points in the power system where disturbances can occur. In order to increase facility reliability and protect equipment, personnel and business operations, it is necessary to properly maintain electrical systems. This is where the important role of the electric power system studies and analysis. In this area a power system study consultant will play his role.

Benefits of Power System Study
As we already know that a reliable and safe power system is essential for a successful operation. A well-designed power system ensures robust performance and maximizes plant availability in all operating conditions, including transient conditions such as motor starts, non-linear loads and generator losses.
The effects of a poorly designed system including power outages, interference, poor power quality, and excessive arc flash can result in significant loss, or worse, personal injury.
The losses caused by disruption of the electricity supply are expensive. That is why it is so important that the electrical system is functioning properly to ensure operational reliability, whether on the side of the power producer, transmission and distribution operator, or on the consumer side. This applies whether you are building a new facility or optimizing an existing one.
In the electrical aspect, companies face many risks which affect all aspects of their operations. Using special power system studies can prevent or solve operation problems, electromagnetic incompatibility and equipment breakdown. Some of these studies are required to verify system compliance with applicable standards and regulatory requirements.
