DATA CENTER POWER GENERATION (GENSET)
The massive growth of data center in Indonesia turn us to develop the needs of power generation. Data-center spend millions of dollars on backup genset, which more often than not amounts to diesel generator sets similar to the regular industrial genset.
There are several questions before purchase a back up genset. First step is to determine what power-distribution infrastructure will meet the data-center’s needs.
- SPACE. Understanding the raised-floor area, heat load, and square area or number of racks. That will help to estimate the total power consumption needs. The outcome will tell you the approximate size of the required power system.
- STRUCTURE. Define the chosen reliability architecture for the facility, use guidelines such as the tier levels to drive the power-system architecture decisions. This will determine how power gets to the critical loads.
- Implementing standard power-distribution system architectures, especially when paralleling multiple generators, because this will increase reliability and enhance serviceability.
What to look for in Backup Generator
- Data-center gensets customised design specifically for this task, and that includes getting to full speed in seconds. It also means being able to accept full-power loads without affecting the load performance. The engine coolant must be kept at operating temperature. For larger generator sets have multiple starters to rotate that much mass quickly when starting.
- Tier rating and power requirements will determine the controls on the generator sets. Redundancy and reliability of the control systems that switch generators online or control several generator sets running in parallel are critical.
- Modern generator sets have digital controls. Assure the digital controls are not an afterthought — you should include digital controls in the initial design of the power-generation package.
- Having digital controls allows remote monitoring and control capabilities. Data-center operators can observe engine and alternator data, control system status, power-transfer status, power-transfer connection status, and load levels without leaving the NOC.
Total power requirement of a typical data center for IT infrastructure includes lighting load, air-conditioning load, and other critical IT loads that include power required by network and communication equipment, desk-tops, servers, and the Electronic Automatic Private Branch Exchange (EAPBX). In addition, power supply is required for security systems such as access control, CCTV surveillance and fire alarms, and Uninterrupted Power Supply (UPS) loads based on redundancy requirements.
The importance of redundant power backup in a data center cannot be undermined in ensuring fail-safe and continuous availability of data and resources. When businesses require only a brief period of extended run-time during a power outage, UPS protection can be provided through supplemental batteries. Applications and users can be signaled to take necessary action before the exhaustion of the limited back-up time available. Systems can be commanded to shut down gracefully. This eliminates all hassles involved in abrupt termination of operations. However, most businesses today operate in mission critical environments, where shutdown of systems as an option simply does not exist. Also, provision of back-up power for protected loads in case of an outage brings with it the accompanying cooling requirements for the operating equipment, which if not satisfied can cause permanent damage to the systems on account of overheating.
Role of Standby Generators
A standby generator is the most viable and affordable option for handling uninterrupted power supply and the concurrent cooling loads in the event of long outages. When configured properly this electrical backup system that can operate automatically in the case of a power outage. An automatic transfer switch senses the power loss within seconds of a utility outage, signals the generator to start functioning, and then transfers the electrical load to the generator. The generator then begins to supply power to the circuits. When the utility power supply is resumed, the electrical load is transferred back to the utility by the automatic transfer switch. The standby generator shuts off and moves into a standby mode where it awaits the next outage without interfering with the functioning of the utility power.
We design and develop for the needs of Back Up Power Generation (Genset) Data Center. Our Gensets are customised to meet the TIER 4 requirement.
