Yuhuu~

Today, I went to NERCC (North Eastern Regional Control Centre). I have learnt how to take load reading which is used for load forecast planning. Load reading is a monthly event and it is useful to predict expenses in the future by taking the load reading for each place in the north and eastern. NERCC is placed in the TNB building level 5 in Seberang Prai, Pulau Pinang.

NERCC acts as switching control centre. It controls all the switching of the PPU and PMU (33kV and 11kV). The technician talked about SCADA (Supervisory Control and Data Acquisition) system it to us. They said, “SCADA ni bertujuan memastikan bekalan elektrik ke Wilayah Ekonomi Koridor Utara (NCER) dan Wilayah Ekonomi Pantai Timur (ECER) mencukupi untuk menampung kepesatan aktiviti ekonomi di kawasan berkenaan. Contohnya, system ni dapat mengesan sebarang kerosakan atau masalah berkaitan bekalan elektrik bagi kawasan terbabit dan tindakan memulihkan bekalan akan dilakukan dalam jangkamasa yang cepat. Kalau ada kerosakan kecil, TNB boleh mengambil tindakan awal untuk memulihkan keadaan bagi mengelakkan kerosakan menjadi lebih buruk.”

Pulau Pinang became the second RCC (Regional Control Centre) in Malaysia after Bangsar in Port Klang. Other than that, MSRCC (Metro South Regional Control Centre) in Bangsar distribute the electricity supply to the south and western part of Malaysia.

In the PMU and PPU, there is RTU (Remote Terminal Unit). All the value measured and the data of the load is connected to it and the data will be sent through transducer in the RTU to RCC.

We can get the idea by finding the value from the load reading. the method of reading the value ca become tedious if the value given is not specified whether it is in the morning or night. So, we need to do a comparison at specified time throughout the month.






Then we went back home. We finally reached at the company at 6.10 pm. So from the punch card, it’s looked like we did an overtime work with “no salary”.

that's all for today
bye~
