Electrical system engineering studies and practical recommendations

Electrical system engineering studies and practical recommendations

It allows you to save money and time.

Since 2002, we have conducted good studies on the power system of refineries, petrochemical plants, and power plants and have gained good experiences. Our expertise in power systems, which is constantly growing, includes command of any monitoring equipment and the use of advanced analytical software with dynamic simulation. No matter how complex the problem may be, we are confident in providing elegant and original solutions.

Optimize your power system

We offer a full range of energy system studies, along with analysis and design for efficient use of electrical energy and high voltage equipment. At least our service areas, but not limited to them, are:

A comprehensive study of the electrical system and the design and determination of the basic parameters of the equipment

Determining the arrangement of the network and how to connect equipment, transformers, generators, motors, etc. And determining their correct parameters is necessary to optimize the system and a correct design can guarantee the performance of the system. Different grid arrangements, cases and points of paralleling generators and generators with the grid should all be properly studied and the effects of each arrangement should be considered.

Arc Flash Study

This study identifies the specific risk of arc flash for electrical equipment in a facility. Provides actual calculated short circuit current, trip time and incident energy (arc flash energy). The program also explores coordination to reduce the energy level of the arc flash, while focusing on eliminating nuisance trips, both during ground faults and phase faults.

Short Circuit Study and Analysis

We look at fault currents in short-circuit currents. Although this is similar to an arc flash study, in some cases the arc flash may not be obvious, but short circuit currents are still present and must be analyzed for the best protective performance of the system. This study is usually part of an overall protection and coordination study where the settings of relays and protective equipment are also optimized and modeled.

Protective Device & Relay Coordination

With the aim of reducing disturbing interruptions in the operation of electrical equipment and preventing the interruption of unnecessary items when an earth or phase fault occurs. Proper coordination along with the right size of protective equipment also helps in a useful operation.

Load Flow and Transient Flow Study / Voltage Drop and Motor Starting Analysis

It is considered to check the overall ability of the electrical system to adequately supply the connected load and thereby reduce breakdowns and outages due to heat or stress, and voltage below the rated value of the equipment. Electrical system load analysis can lead to recommendations to increase maximum output while reducing operating costs.

Harmonics Analysis – Harmonics Analysis

This study is necessary to meet the user needs at the point of common connection (PCC) and thereby reduce the unavoidable electricity costs. This inspection can reveal areas where preventable electrical losses occur, which reduce the efficiency and insulation properties of electrical equipment. Harmonics can cause some electronic devices to malfunction, as well as unexpected heating of transformers, motors, capacitors, etc.

Power quality measurement and analysis

Similar to the nature of harmonics analysis, power quality measurement and analysis monitors how close power is to optimal characteristics.

Investigation and analysis of power system errors

Engineering analysis to identify the cause of equipment failure or where a failure has occurred or may occur in the future; To prevent a similar incident in the future. It is important to know that when investigating, sometimes there may not be a clear cause for an outage that occurred, and in such cases the root cause of the outage cannot be identified. This is usually acceptable to customers who want to know the most likely cause for future prevention.

Evaluating the interaction effect of grid / power generation plant

This type of study takes on various names and variations, but is essentially research on behalf of the customer to determine the feasibility and costs of connecting to the network (usually as a generating connection) and potentially to initiate the processes required and Other regulatory matters are involved.

Earth network design and analysis

The design of the ground network, especially for substations, requires a sufficiently engineered ground network so that during major faults, the touch voltage (such as the voltage between the legs and a hand on a railing, for example) and the step voltage (the voltage between the legs during a step). ) to be sufficiently compliant with regulatory and accepted standards. Factors such as soil/sand resistivity, network depth, conductor sizes, conductor lengths, humidity, etc., can all be modeled (or manually calculated) to ensure that the network design is predictive of power system or substation capacity. is enough

That’s why you may often hear about a downed power pole requiring special precautions (ie: walk away with a pair of feet). While the fault in the substation is probably engineered, it is still very dangerous!
