The total electricity supply grew 4.12% over the same period in 2012.

 Abstract 

The main purpose of this study is to explore the application 

in  campus  carbon  reduction  issues.  According  to  campus 

energy consumption,  the power monitoring  system  records 

basic  information  of  electrical  load  about  the  campus  air 

conditioning  systems,  lighting  systems,  thermal  systems, 

and  training  equipment.  The  energy  situation  is  observed, 

the  data  is  analyzed,  and  then  recommendations  for 

improvement  are  suggested,  in  order  to  achieve  energy 

conservation on campus.

Energy Conservation; Power Monitoring System  

Introduction

Taiwan  is  a  country with  limited  indigenous  energy, 

and  its energy  requirements  force  the country  to  rely 

on  foreign  imports. Any  fluctuations  in energy prices 

affect  the  nation’s  industrial  production, 

transportation,  commercial  activities,  and  even  the 

costs  of  peopleʹs  lives.  Saving  energy  and  reducing 

carbon  emissions,  therefore,  have  been  a  necessary 

and  inevitable  trend  (Kamalapur  and  Udaykumar, 

2009; Wei, Xiaodong and Wei, 2010). Schools must also 

meet  the  government’s  energy  conservation  policies 

by  implementing  energy  saving  ideas. How  to  avoid 

energy  waste  and  reduce  electricity  costs  are 

important issues. 

Taiwanʹs trade and industry has developed rapidly in 

recent  years,  resulting  in  a  significant  increase  in  its 

power  consumption. The power  system peak  load of 

167 GW  (Giga Watt)  in  1991  increased  to  271 GW  in 

2002. With  the  recent  economic  growth,  the  annual 

electricity  consumption  also  increased,  with  stable 

growth in the period of January to July 2011. The total 

electricity supply grew 4.12% over the same period in 

2012.  On  July  16,  2011  from  2  pm  to  3  pm,  due  to 

weather  changes  from  high  pressure  to  a  hot,  high 

temperature,  Taiwanʹs  average  hourly  electricity 

consumption  of  33.13 GW,  exceeded  the  July  7,  2010 

record high of 33.02 GW at peak  load (Taiwan Power 

Company, 2014). 

The month  of  electricity maximum  required  amount 

sometimes  exceeds  the  contracted  capacity.  The 

following criteria will be collected  in accordance with 

the  Taiwan  Power  Company  tariff  table  (Electricity 

Price  Table,  2014),  which  provides  the  basic  tariff. 

When  the  Electricity  consumption  is  exceeding  the 

contrast  capacity  below  10%,  then  the  basic  tariff 

doubled.  When  the  Electricity  consumption  is  10% 

greater  than  the  contract  capacity,  then  basic  tariff 

tripled. The  question  is  how  to  get  high  quality  and 

inexpensive  electricity.  That  is  the  main  objective 

when automating power monitoring and management 

system. 

The application of a power monitoring system  is able 

to  increase  the  level  of  information  technology  and 

networking, so  that  the  function of  the power system 

is  no  longer  limited  to  simply  supplying  electricity. 

Not only does this allow for immediate understanding 

of  the  electricity  situation,  but  it  also  provides  a 

variety  of management  and  control  services  that  can 

be  employed  to  enhance  the overall  energy usage. A 

power monitoring system can also play an  important 

function  in  power  demand  control  during  peak 

demand periods. 

There are many vendors in the industry that can install 

and maintain power monitoring systems, for example, 

Shihlin  Electric  &  Engineering  Corporation  (Shihlin 

Electric &  Engineering Corp.,  2014), Nan Ya  Plastics 

Corporation  (Nan Ya Plastics Corp.,  2014),  and KLD 

Technology  (KLD Company,  2014),  for  example. The 

technology  and  talent,  however,  lacks  some  of  the 

relevant  technical  information,  and  very  few  school 

textbooks can be used because almost none of the texts 

provide  the  necessary  information  for  technical  and

vocational  institutions  or  suit  the  industry  for 

developing  the  relevant  technical  personnel  to  cope 

with the needs of industry. 

Under  the  limited  speed  of  the  development  of 

electrical energy, electrical energy conservation is even 

more  important  when  aiming  to  achieve  energy 

savings,  which  is  very  important  when  monitoring 

electricity  use.  This  study  combines  content, 

communication,  computer,  and  control  (the  4Cs  of 

technology),  in  order  to  design  and  plan  the 

professional  competence  of  power  monitoring 

programs and course materials. 

Intelligent Power Monitoring System

In  Tung  Nan  University,  the  intelligent  power 

monitoring  and management  system  (Wu,  Kuo, Wu 

and Wu, 2007; Wu, Kuo, Yen and Wu, 2008) can be the 

remotely  controlled  to  monitor  campus  energy 

consumption, effectively improve the efficiency of the 

campus  electricity,  and  save  electricity  costs.  Energy 

conservation  is  very  useful.  Monitoring  the  host 

computer through the network communication system 

can  help  to  transmit  electric  power  throughout  the 

campus  to each building and substation devices with 

multi‐function digital meters. The  site data  collection 

hosts  and  other  facilities  administer  each monitoring 

point  and  collect quality and volume  statistics of  the 

electricity  in  order  to  construct  a  web‐power 

responsibility center management system. The system 

functions are as follows: 

(1)monitoring the power quality of the school, the total 

electricity consumption, and the peak demand volume 

and other conditions; 

(2)using  the  control  software  to  monitor  the  usage 

statistics  of  campus  energy  and  reporting  database 

management; 

(3)ensuring  that  peak  demand  does  not  exceed  the 

contracted capacity in order to decrease surcharges; 

(4)designing  real‐time  display  bulletin  board  for 

advocacy education and energy‐saving; and 

(5)establishing a power control center.

The Specific Measurement of Energy Savings and Performance

From  2008  to  2013,  the  total  amount  of  electricity 

consumed  decreased  year  by  year  (Information  of 

Electricity  Consumed  in  Tung  Nan  University),  as 

shown  in  Table  1.  For  example,  in  2009,  the  total 

reduction was 324,400 KWH (4.4%) from 2008; in 2010 

the reduction was 381,600 KWH (5.4%) from 2009; and 

in 2011,  the  reduction was 296,800 KWH  (4.4%)  from 

2010.  The  school  has  completed  the  specific  energy
