Calvin is developing plans for a new data center to provide business continuity and quick recovery in the event of a disaster. The new data center will not replace the existing data center; rather, it will provide redundancy for the operations of the campus. This new data center will be placed in the Spoelhof Complex. Because of the energy demands of data centers, there is a worldwide push for energy efficiency. So-called “green data centers” provide the same functionality as a normal data center with reduced energy usage and reduced energy costs. Calvin, like most organizations, must weigh the long-term …

The new redundant data center requires that Network Operations Center personnel are able to monitor certain conditions within the data center for the safety of the server equipment. Server equipment will fail if it gets too hot or if the surrounding environment becomes too humid, therefore the baseline instrumentation design must monitor both temperature and humidity in the data center. The system must also be capable of remotely alerting NOC personnel when there is a problem.

Harmonic Distortion State Estimation Using An Evolutionary Strategy, Elcio F. De Arruda, Nelson Kagan, Paulo F. Ribeiro

University Faculty Publications and Creative Works

This paper presents a new methodology to estimate harmonic distortions in a power system, based on measurements of a limited number of given sites. The algorithm utilizes evolutionary strategies (ES), a development branch of evolutionary algorithms. The main advantage in using such a technique relies upon its modeling facilities as well as its potential to solve fairly complex problems. The problem-solving algorithm herein proposed makes use of data from various power-quality (PQ) meters, which can either be synchronized by high technology global positioning system devices or by using information from a fundamental frequency load flow. This second approach makes the …

2010 Spring Engr333 Project Assignment, Matthew K. Heun

ENGR 333

The Spring 2010 ENGR333 project assessed options for the design of a redundant data center for the Calvin campus.

I asked the students “What would it take to build a redundant data center at Calvin that is 30% more energy efficient than the existing data center?”

Note: Because I was on sabbatical in Fall 2009, ENGR333 was moved to Spring 2010.

A Pll-Based Multirate Structure For Time-Varying Power Systems Harmonic/ Interharmonic Estimation, Janison Rodrigues De Carvalho, Carlos A. Duque, Moisés V. Ribeiro, Augusto S. Cerqueira

University Faculty Publications and Creative Works

This paper describes a phase-locked-loop (PLL)-based power systems harmonic estimation algorithm, which uses an analysis filter bank and multirate processing. The filter bank is composed of bandpass filters. The initial center frequency of each filter is purposely chosen to be equal to harmonic frequencies. However, an adaptation strategy makes it possible to track time-varying frequencies as well as interharmonic components. A downsampler device follows the filtering stage, reducing the computational burden, especially because undersampling operations are performed. Finally, the last stage is composed of a PLL estimator which provides estimates for amplitude, phase, and frequency of the input signal. The …

2006 Fall Engr333 Project Final Report, 2006 Fall Engr333

ENGR 333

The objective of this project was to demonstrate Calvin’s interest in alternative energy. The development of a short-term plan to implement a demonstration wind turbine and a long-term plan to determine the feasibility of a larger turbine for the future demonstrates this interest. The class was divided into five teams: management, external relations, long-term technology, short-term technology, and campus infrastructure. While each team had its own objectives, everyone worked together to share information and accomplish the overall project goals. This management technique provided necessary structure and simulated an environment typically found in a career environment.

The goal of the project was to construct a realistic plan to get Calvin off the grid. This means that Calvin would own and operate on-site facilities that generate all the electricity consumed by the campus. Current peak load for the college is approximately three megawatts. Upon completion of the new recreation center and dining hall renovation, future load will climb to roughly five megawatts. As a result, the desired system to remove the college from the grid would provide five megawatts.

An energy savings plan for Calvin College has been developed. The plan suggests implementing a small-scale wind turbine pilot program and an energy usage awareness program (Powerful Savings). If implemented, this proposal could save around $6,400 annually with a payback period of 8 years.
