Electrical power system built in any facility needs appropriate protection strategy for safe & reliable system operation. Undetected and sudden electrical system faults can become hazardous and disturb the operation of entire system, critical devices and causes the overheating, unbalanced system conditions, interruption of the system supply and blackouts etc.
Power system analysis studies from Care Labs provide you with an insight into where critical points occur in your electrical network and how you can optimize, control and positively manage electrical power.
Power system study & analysis is essential to understand the performance of power systems under specified conditions.
There are many types of power system analysis study, each one with their own special purpose and method of calculation. Each of these studies is unique to a particular electrical power system, any changes within the system can affect the results of the study and requires recalculation.
Care Labs provide comprehensive Power system study & analysis for all types of facility in Mexico.
Load flow analysis:
A load flow study determines the active and reactive power, voltage, current, and power factor throughout the power system. This study provides an analysis of all possible operating scenarios of the electrical system and identifies overloaded equipment.
ETAP power flow analysis software module provides an extensive load flow analysis set and tools to simulate calculation of bus voltages, branch currents, power factors, and power flows throughout the electrical system.
It is performed to obtain following results:
- Evaluate the system’s capability to adequately supply the loads connected
- Prevent overloading of equipment
- Compare equipment operating values with manufacture specified maximum capability rating
- Indicate any under or over voltage of any bus or node
- Calculate system losses, power factor correction, and voltage drop
We utilize powerful power system transient analysis software ETAP to perform all types of power system study & analysis.
With the help of extensive set of load flow analysis & simulation tools in ETAP load flow analysis module, we calculate bus voltages, currents, power factors, and power flows throughout the system.
Short Circuit Analysis:
The short circuit analysis is required in order to provide data for the selection of protective devices, their settings and stability of system operation. These faults, may occur in all three phases symmetrically, or may be asymmetrically.
This analysis used:
- To find the available short circuit or fault current
- To determine the required interrupting capacity of protective system
- To predict the incident energy levels
- To ensure that people and equipment are protected by protective devices with proper interrupting ratings
Using ETAP short circuit module, we analyse the effect of both balanced and unbalanced short circuit faults and comparing these results against manufacturer short circuit ratings. Then determine optimal and worst-case operating conditions of fault current, device duty with plots and reports. Overstressed equipment is displayed on the single-line diagram, and in reports.
Protective Device Co-ordination Study:
Fault in one location should not affect the function of another critical element in electrical network. Such cases may occur if protective devices are not properly coordinated among other resulting in supply interruption which was not required. With coordinated power system, nearest protective device will operate first so that power outage is minimized.
ETAP provides intelligent power system analysing tools and powerful capabilities to analyse protection system and troubleshoot false tripping, device mis-operation, mis-coordination.
