Dpstar’s broad portfolio of substation automation solutions provides customers with the control and automation functions needed to build a smarter, more reliable power grid.  Our team of engineers has over 30 years of experience with designing and configuring protection systems for electric power substations. Dpstar electrical monitoring system is designed for use within utility, commercial and industrial facilities. Dpstar monitors and analyses the electrical flow within a building to provide a more in-depth analysis of the electrical network. Data is collected and presented as actionable information that helps to meet energy saving targets and reduce costs. This enables us to provide advanced solutions that monitor various metrics that have adverse effects on electrical systems. At Dpstar, we understand the critical in maintaining efficiency, minimize downtime, communicate issues, and provide real-time data for smarter business decision. We can help you to better understand your electrical system and ensure its running safely and reliably. Our solutions deliver a smart, cost-effective, short-cycle solution for digitized substations that are scalable to meet the varying needs of utilities across the globe.

An electrical substation is an essential part of a complex system that delivers electric power from where it is produced to where it is consumed. The control system equipment in a substation is a vital part that supervises, protects and controls the transmission of electrical power. The increasing complexity in today’s substations, together with the increasing transmitted power and fault current levels, means increasing requirements set on the control and protection equipment. Monitoring systems can limit the exposure of personnel to potentially hazardous electrical environments by providing remote status and operational parameters of equipment within hazardous areas. Some monitoring devices also offer a variety of additional parameters (temperature, pressure, flow rate, vibration, status indicators, etc.) through the use of transducers. The purpose of this project is to analyze and troubleshoot the problem as soon as possible to protect their high-value assets and to improve their continuous service to their clients. This allows for closer monitoring and ensuring that everything is working properly and providing power to the appropriate end-users.

Dpstar designed and built an electrical control and monitoring system for the TNB substation in Cameron Highlands using SIEMENS S7-300 PLC and SCADA system to monitor critical alarm points and control of remote equipment throughout the facility. In order to improve the operational efficiency of the transmission grid, Dpstar has upgraded the substation protection control system into a new automation system for the TNB substation. Our electrical control and monitoring system make their control and monitoring possible in real-time and maximize the availability, reliability, and safety of the system. SCADA system interacts with PLC for the implementation of the whole process. PLC ladder logic is used to check the status of various equipment such as circuit breakers, isolators, and ground, to automatically perform the sequential process of opening, isolating, and grounding involved in a line outage. Operators now can see and check the position of the whole process on the SCADA screen in order to reach a strong conclusion about their actual impact on the power grid monitoring and control without manpower.

The advantages of the proposed system are bypass circuiting without any interrupt, manpower is reduced, the time delay is reduced, and personnel can monitor the plant in the control room itself and give commands through the user. Any modification or future extension can be easily updated in PLC & SCADA, it is cost-effective for controlling complex systems, troubleshooting aids make the program easier, it is flexible and can be quickly and easily reapplied to control other systems.
