Essential Standby Generator System Requirements for Next Generation Data Centers

White Paper 90

Standby power generation is a key component of a high availability power system for data centers and network rooms. Information technology systems may operate for minutes or even a few hours on battery, but local power generation capability is key to achieving high availability. In locations with poor utility power, local power generation may be needed to achieve even a minimal requirement of 99.9% availability.

Generator systems with diesel or natural gas engines are, in most cases, the solution for standby power generation. A generator system includes not only the standby generator, but also the automatic transfer switch (ATS), the output distribution, and the communication or management system as shown in Figure 1. The ATS is fed by two sources, the utility and the generator, with the utility the preferred source. When the preferred source is unacceptable, the ATS automatically switches to the generator. White Paper 93, Fundamental Principles of Generators for Information Technology, provides a detailed explanation of the operational principles of generator systems.

Standby generator systems are typically used in conjunction with UPS systems. There are several issues that need to be considered when choosing, installing and operating a generator system that operates seamlessly with a UPS. This paper outlines the key problems and requirements for effective selection and operation of a generator system to support today’s mission critical data centers.

Executive Summary:

Effective standby generator system installations must address the known problems and challenges relating to current and past designs. This paper presents a categorized and prioritized overview of generator system challenges and the requirements needed to overcome them.

Contents:

  • Inadequacy of current generator systems for IT managers
  • Generator system challenges in mission critical installations
  • Standby generator systems for mission critical installations

Conclusion:

A systematic analysis of customer problems relating to generator systems provides a clear statement of direction for next generation systems. The most pressing problems related to generator systems today stem from the custom approach to their design, installation and maintenance. Legacy systems require site specific engineering and installation expertise that not only increases capital costs but also increases operational costs due to their unique management and service requirements.

In many industries, a maturity level is reached when new advances in reliability, cycle time, and cost lead to standardization and pre-engineered solutions. Designers of mission critical installations, designers of the power equipment used in them, and owners should consider whether this point has been reached.

The findings of this paper suggest the time has arrived for a new generation of integrated standby generator systems for mission critical installations.

APC Smart-UPS On-Line Features and Benefits Overview

Posted by on February 6, 2012  |  No Comments

A versatile UPS developed for the harshest power conditions in the world.

Smart-UPS On-Line provides high density, true double-conversion on-line power protection for servers, voice / data networks, medical labs, and light industrial applications. Capable of supporting loads from 1 to 20kVA in a rack/tower convertible form, the Smart-UPS On-Line is available from 2U to 12U. Recent family extensions at 15 and 20kVA enable support of power hungry blade servers or heavily loaded equipment racks. When business-critical systems require runtime in hours, not minutes, Smart-UPS On-Line can be configured with matching battery packs to comply with aggressive runtime demands. The included PowerChute management software provides unattended graceful shutdown of network operating systems. All models 5kVA and above include an integrated Network Management Card for remote management (optional on models below 5 kVA). The entire Smart-UPS On-Line family provides value to customers with demanding power environments, including very wide input voltage window, extremely tight output voltage regulation, frequency regulation, internal bypass, and input power factor correction.

John Precopio gives a brief overview of Smart-UPS On-Line and it’s key features and benefits.
