Project Management & More
PowerCom offers individual solutions to demanding work schedules. Since shut downs often occur during holidays, major expansion projects and off peak hours, facilities have a limited amount of time and resources to accomplish plant modifications and upgrades. This makes it necessary to have competent, experienced Engineers with the complete knowledge and understanding of your particular facility and its equipment.
The Engineers at PowerCom have a wide range of experience from the manufacturing segment to the support and maintenance of nuclear and fossil generating stations. Our temporary placement of Engineers and specialized technicians is essential in completing numerous on-going projects in a safe and timely manner. Our engineers have experience managing all aspects of new construction projects; from the design to the commissioning of new facilities. We have the resources to manage everything from small to multi-million dollar projects.
PowerCom also offers complete facility management and maintenance staff for short-term and long-term projects. Our staff will maintain all aspects of your facility to ensure continuous and efficient operation for the duration of your needs. This includes facilities such as industrial, manufacturing, hospitals, utilities, retail, and office complexes. PowerCom supplies qualified personnel for all specialized trades, including professional engineers that will assist your company’s needs for as long as you need us.
ELECTRICAL EQUIPMENT EVALUATION
PowerCom can compare your protective device ratings with short-circuit calculations from a short circuit study. The program we use also compares continuous ratings of your equipment to calculated design and operating conditions. Equipment that fails the evaluation are reported in table format and are color-coded by the one-line diagrams. PowerCom can then give recommendations on how to correct the issues as to why your equipment failed the evaluation test.
ONE LINE DIAGRAMS
A One-Line Diagram is a simplified schematic diagram of a power system. It serves as a blueprint for electrical engineers and is a key tool when troubleshooting potential issues with load flow, coordination and protective electrical equipment. PowerCom has the ability to draw, modify and model One-Line Diagrams of your facility’s electrical system.
An electrical fault is the deviation of voltages and currents from nominal values or states. They can be caused by equipment failures such as transformers, rotating machines, human errors and environmental conditions. Faults cause interruption to electric flows, damage to equipment and can even cause death. Using our software, PowerCom can simulate existing conditions and allow the program to provide a solution to Symmetrical and Asymmetrical faults, if any exist. At each fault location, the direction, X/R and magnitude of fault currents are reported, thus providing a clear understanding of the conditions that exist during the fault.
LOAD FLOW & VOLTAGE DROP CALCULATIONS & ANALYSIS
Load-flow studies are performed to determine the steady-state operation of an electric power system. Our software allows us to calculate the voltage drop on each feeder and transformer branch, the voltage at each bus, the power flow in all branch and feeder circuits and the losses in the power system.
PowerCom can determine if system voltages remain within specified limits under various contingency conditions and whether or not equipment such as transformers and conductors are overloaded. We can also identify the need for additional generation, capacitive or inductive VAR support, while also identifying the need of placements of generators, capacitors and reactors to maintain system voltages.
DEMAND - LOAD ANALYSIS
PowerCom specializes in conducting load studies which analyzes power availability and usage within a system. Our software allows us to calculate the connected demand and design loads flowing in the branch circuits of your electrical system. An on-site load study will take a minimum of a week in order to properly monitor usage and distribution capabilities (Power Quality Monitoring). PowerCom can use the program to mimic different scenarios for changes, expansions or additions to the loads of your electrical system. The information gained from a load study allows for easy decision making when choosing which path to take when starting a project at your facility.
