When designing an electronic network infrastructure as a component of power system studies, protective device synchronization is a crucial component. For power distribution research, protective device coordination is also referred to as selective coordination and relay coordination.

Relay coordination studies' main objective is to gather information needed for short circuit coordination research findings, modelling of protection relays, and many other overcurrent protection devices for power system studies.

Relay Protection Coordination Services are offered by VB Engineering following IEEE, IEC, and NEC standards. Even the protective device coordination research is done by VB Engineering.

For data collection, VB Engineering utilizes the VB Tantra digitizing app. Depending on the needs of the customer, SKM or eTap protection coordinating software can be employed.

Relationship Between VB Engineering And Relay Coordination Studies:

Phase 1: VB Engineering’s Version Of Gathering All Data

VB is an innovator in the field of relay coordination studies. We have developed a systematic data-gathering process for relay coordination studies using the knowledge we've gathered from doing short-circuit protection relay services.

Our committed team of electrical experts will be at your place on time. Utilize the VB Tantra smartphone app to get all the necessary data.

We require the entire behaviour manual for the electrical installations at the factory to calculate the relay configuration.

Power system relaying is designed by OEMs following a widely accepted worldwide standard, and the manufacturer will have predetermined guidelines for the equipment's behaviour.

Phase 2: Research On SLD Setup, Circuit Breakers, And Relay Coordination 

As soon as the OEM collection for protection relay in power system studies and the information required for carrying out short circuit coordination studies is calculated, VB Engineering will check incoordination by employing the SKM or etap protection coordination study software package.

To determine the overcurrent relay coordination in the system, the loading circumstances and the short circuit research results will be computed and recorded in the SKM or etap relay coordination unit.

When our back-end team receives the results from the VB Tantra mobile platform, we simulate the information using the reputable electrical modelling programs SKM or eTap.

A variety of numerical simulations, including voltage drop analyses, short circuit research, and protective device coordination studies, will be performed on the modelled infrastructure.

The fault current calculation must be performed to determine the maximum allowable fault current at every feeder and bus. The parameters of the 3-phase clamped and arcing fault are provided by the IEEE short circuit current calculation sheets.

To do relay coordination calculations, we must use the results of the short circuit computation. The computation of the relay setting will be based on the time data and the fault current computation.

Phase 3: Outcomes Computation and Complete Review

After determining the over-current protection needed for the system to resist load and short-circuit currents, the VB Engineering team will employ the SKM or Etap relay coordination software package to evaluate for network miscoordination.

In our power system evaluations for developing the operation as a standalone executable, the relay protection coordination solutions are included.

For comparison with current naturalistic settings and ratings, the values and evaluations of each protective device, such as fuses, motor controllers, circuit breakers, and many more, as assessed by the analysis are stored in a table.

We give the results after thoroughly preparing the final report following international standards.

VB’s Victory Formula: 

Power system analysis plays a crucial role in the operation of any electrical design. For proper functioning, all plants and facilities undergo a classical power system analysis that includes a relay coordination study or computation.

Studies of relay coordination are essential for electrical upkeep and plant operation. To ensure an effective problem detection and fault clearance process, relay coordination is employed. These relays would have to be able to distinguish between persistent overcurrents caused by fault situations and short-term overcurrents that may emerge owing to specific equipment's regular functioning, such as motor starting currents and transformer inrush currents.

Overcurrent prevention and power system relaying are interdependent ideas that support a plant's efficient functioning. We must carefully carry out the power system protection and the protective device coordination research without jeopardizing the electrical safety of the system to accurately offer overcurrent protection.

By correctly calculating the protection relay configuration and initiating power system protection, the primary goal of protection coordination is to prevent nuisance tripping. These relays must react rapidly in the event of a malfunction to isolate the affected area of the network and maintain the functionality of the healthy circuits.
