Jurong Datacenter

Singapore

This is one of Singapore’s leading-edge datacenter facilities that features robust power and mechanical architecture.

– 7-storey, 375,000 sq.ft

– Dual redundant 22KV mains, 6 MVA power transformers in N+N

– 6 MVA Gensets N+1

The PMS, based on FMC’s UCOS & ION Enterprise oversees the electrical distribution within the facilities to ensure stability of supply. The PMS interfaces to intelligent devices within:

– MV/LV Switchboards

– Power Transformers

– Static & Dynamic UPS

– Emergency Generators

VL is a specialist sub-contractor to SMB/CSI for the M+W designed PMS System. The VL scope of work includes equipment supply, systems configuration, integration, and on-site testing and commissioning.

Project Details

Power Management System (PMS)

The system is built around UCOS SCADA platform and ION Enterprise as the power analysis tool. The UCOS system utilizes industry standard PC and PLC I/O, providing complete solution for process control and graphical human-machine interface. Operators are alerted to all abnormal conditions such as trips and alarms. The interfaces to all intelligent devices are made via the distributed ICM which is an intelligent multi-ports and multi-protocol communication manager. Meanwhile, the ION Enterprise Server provides very detail power quality analysis for all ION meters and SEPAM digital protection relay installed in both MV and LV switchboards.

Challenge + Solution

Interface with different parties – The power management system needs to monitor equipment and systems from different vendors including emergency generators, UPS, LV switchboard and HV/ MV switchboard and at the same time the PMS also provide data to the Building Management System. To ensure all data from different equipment are collected effectively, a number of ICM are strategically distributed in different locations of the datacenter to collect power related information. Meanwhile, OPC is also used to allow BMS to efficiently obtain data from the PMS.

Compressed Test & Commission (T&C) Schedule – The PMS working schedule is highly influence by the working schedule of all parties. Any slip will usually compress the PMS schedule. Therefore detail planning is required and advance work for standardization of interface type carried out to reduce changes on the spot.
