Power supplying method of electrical power system with high-powered and high-voltage diesel generating set for large data memory center

Abstract

The invention discloses an electrical power system with a high-powered and high-voltage diesel generating set for a large data memory center and a power supplying method thereof. The electrical power system comprises the high-powered and high-voltage diesel generating set, a transformer, a mains wire inlet device, a dual power supply control cabinet, a low voltage distribution center, an emergency power distribution cabinet, a parallel UPS (uninterruptible power supply) system, a DC / AC (direct current / alternating current) distribution box, an IT (information technology) center, a fire fighting system, an illumination system and a lift system, wherein the parallel UPS system is provided with a maintenance system; and the high-powered and high-voltage diesel generating set is provided with a lightning and surge protection device. All the functional modules are matched with each other so as to rapidly start the high-powered and high-voltage diesel generating set to output stable and reliable power in time during the process of examining, repairing or interrupting the mains and avoid the damage, data loss and the like of sensitive devices of the IT center due to the interruption of power, so that the IT staff have more time to sequentially start a backup generator to ensure the matched larger data memory center to stably operate.

Description

technical field [0001] The present invention relates to the technology in the field of electric power systems, and in particular refers to a method of power supply for power systems of high-horsepower high-voltage diesel generator sets in large-scale data storage centers in banking, securities, insurance and other financial industries. Background technique [0002] The operation process of banking, securities, insurance and other financial industries is actually the operation of the entire data system. The entire data system is generally divided into storage modules, database modules, application modules, etc. Among them, the storage module at the back end is a large data storage center. It is the most critical part of the entire data system. It usually requires non-stop application and non-interruption of data storage update, so as to effectively ensure that its data will not be lost or can be recovered as soon as possible after loss. We are very clear that data loss for an...

Problems solved by technology

[0003] At present, due to special weather damage to the power transmission system, artificially disconnected power cables, or limited supply of power due to excessive demand of the power grid, it is very common for power outages to cause data loss or damage in hard disks.

Usually, if there is a predicted power outage, we can prepare for power generation in advance, or, for general small electrical equipment, such as a few computers, we can choose to configure an uninterruptible power supply (UPS) to meet the power supply in time after a sudden power outage equipment, and for large-scale data storage centers, it is difficult to meet the application needs through ordinary uninterruptible power supplies in response to sudden power outages. Power interruptions often cause damage to sensitive equipment and data loss, while ordinary uninterruptible power supplies The power supply is also difficult to ensure that IT personnel have enough time to start the backup system or generator, etc., so it is difficult to ensure the security of information resources
