POWER SYSTEMTHE GROVE by ROCKWELL

POWER SYSTEMIt is a network of electrical component used to supply, transmit, and use electric power. The Grove Phase 1 is supplied from the public utility grid which is Meralco, and with three stand by Generator Sets for back up during power interruptions.TWO TYPES OF POWER

SYSTEM

NORMAL POWER SYSTEM

It is the power supply coming from electrical utility company

STANDBY POWER SYSTEM

This system is a combination of a diesel engine with an electrical generator (alternator) to generate electrical energy.

STANDBY POWER SYSTEM

BASIC SINGLE LINE DIAGRAM

Basically, our power system in all our establishments is supplied by electrical utility company, which in our case is Meralco. At the time normal power is interrupted, our emergency or stand by power system will automatically switch thanks to the ATS and kick in the system. Here is the list of our generators here in The Grove:

RATING

GENERATOR 1 1,256 KW



HOW DOES A GENERATOR WORK?

Picture yourself plugging the cord of a fan into a 220 volt AC power outlet and then you hit the “ON” button and voila, you’ve got a cool breeze of air blowing on you from the fan. In a nutshell, the electricity comes from our electrical utility company, into our establishments or houses and then directly to the outlet that you’re plugged into and that electricity gets the fan blowing.

Generators that produce electricity operate on that same principle, just in reverse! For example, we will take that fan outside not to provide a breeze, but to receive a breeze. As the wind blows, the blades on the fan turns. Attached to the blades is a shaft that goes into an electric generator motor. As this shaft turns, it produces electricity.

RUNTIME CAPACITIES

For the generators to run, we need diesel fuel. This diesel will be burned through the diesel engine, which in turn produces motion for the generator and then this motion will be converted to electricity.

To provide our stakeholders an uninterrupted power supply, we see to it that our day tank and mother tank always have sufficient amount of diesel fuel. As of today, below are the capacities of each tank versus current volume:

Considering that each generator set consumes 256 liters of diesel per hour and given the current volume of each tanks, we could arrive at these runtime capacities:

COMPARISON SYSTEMSPOWER

I took the opportunity to compare our system here in The Grove with some of our other establishments. I was able to gather some data through some of my colleagues. Then I also tried to compare The Grove with other properties of some different developers. Thanks to my friends who are currently involved in other companies, I got the chance to know what is in their properties that we don’t have and vice versa.

SUGGESTIONS

Since Property Management is one of the most critical and important business processes we have, I think that it is best to have a proper training for building engineers like me especially for the new hires because most of them just landed their first job. I have listed some pointers that could definitely improve the performance of Building Engineers, and may yield higher degree of competency.

WHAT DO BUILDING ENGINEERS NEED

BUILDING ENGINEER 101This is similar to the On-boarding Journal our HR Team gives to the new hire, but we will make it more specific. A timetable of activities and discussions/teaching about the basics of the building systems, guidelines and house rules compressed on a 2-weeks period before the actual duty of an engineer.

A follow up seminars and trainings relevant to the existing building systems and to new technologies that can be applied to our towers. This will greatly improve the technical skills of BEs, and it would be better if there will be hands-on activities too. Doing dirty jobs is what most engineers like.

COMMUNICATION SKILLS

REALIZATIONS

One of my mentors said, “there are things which are obvious and there are things which are not.” Producing this output could be the obvious part. But things which are not obvious could be the things transpired on the process of producing this output. I had the chance to talk with some of my colleagues, asked few questions which I could not usually do. I also had the chance to get in touch with some of my friends and gathered some information to them. Most important is I have learned a lot from it. As they say, life is a never ending learning process.
