Background And Purpose Of Load Testing Of Diesel Generator Sets in Data Centers
1. Background overview of data center diesel generator set load bank test
With the large-scale construction of telecom data and the rapid development of various value-added services, the IT equipment in telecom data centers has grown rapidly. Power supply is the basic guarantee for the normal operation of data center IT equipment. Once a power supply failure occurs in the data center, the consequences of data loss are catastrophic. The interruption of telecommunications and electronic information systems will cause significant economic losses or cause financial disorder. According to the data released by the State Electricity Regulatory Commission and the China Electricity Council, the average reliability of 10KV urban users in 2014 was 99.82%, which could not meet the requirements of 99.995% or higher reliability of the power supply and distribution system of important data centers. Therefore, the emergency power system is one of the indispensable and important equipment of the bank data center.
The power safety of the information room is an important guarantee for the normal operation of the information equipment. The power safety problem will greatly affect the work efficiency and the smooth development of the modern management work, including the business outlets. Once the data center is in operation, it is required that the power supply cannot be lost in the slightest. Otherwise, it may cause service interruption, damage to servers, switches, storage and other equipment, and network data interruption and loss. Therefore, it is also very important to ensure that the power supply of the IDC is not interrupted and to provide high-quality power. Power supply is the foundation of the data center. The data center is the place where services are stored. The server is a sophisticated electronic device. Once the power supply is unstable, it will bring great adverse effects.
In principle, the generator must be matched with the UPS and used in combination with the power distribution system to achieve the purpose of normal work. Otherwise, the generator will not only fail to work properly, but also cause damage to the generator, resulting in direct economic losses. .
Power failures are sudden and often not based on people's will. The internal management of power supply departments and hospitals is strict, and the power grid facilities are advanced. Due to network overload, earthquakes, typhoons, serious natural disasters and accidents, it is possible to cause power failure. interrupt. In order to ensure the 24-hour uninterrupted power supply of the computer room, two power supply lines, 2N dual-path power supply and N+1 induction diesel generators enable the T3+ computer room to greatly reduce the downtime when encountering emergencies, making the computer room in normal operation.
2. Purpose of load bank test of diesel generator set in data center
At present, the rating of the data center industry mostly follows China's GB50174-2008 "Code for Design " or TIA-942 of the American National Standards Institute. The grading is defined as Tier 1, Tier 2, Tier 3, and Tier 4. The classification is divided from high to low according to the fault tolerance, redundancy and basic capabilities of the data center.
(1) Detect the output power and load capacity of the diesel generator set in parallel.
(1) When the new installation project of diesel generator set is accepted, check whether it can meet the design requirements;
(2) After the diesel generator set is equipped with noise reduction equipment such as mufflers, check whether its output power can meet the operation requirements;
(3) After the diesel generator set is repaired, check its output power, load capacity and other performance
(4) Routine maintenance inspection and aging identification inspection of diesel generator sets.
(5) Sudden addition and sudden reduction of diesel generator sets, shock resistance test.
(6) Handling small problems in the cylinder and pipeline such as carbon deposits.
(2) Test whether the components such as the PDU in the power distribution room are aging and meet the requirements.
(3) Detecting the output power and load-carrying capacity of communication and AC equipment such as related power supplies.
