xSpider – UPS integrationUPS - introduction

UPS -

Uninterruptible Power Supply - applications:

The purpose of a UPS is to provide uninterrupted power for loads

.

The use of a UPS is typically associated with buildings and applications having critical or sensitive loads

(

ICT, data centres, hospitals, commercial buildings, process industry, ...)

Slide4

xSpider – UPS integrationUPS - introduction

UPS topologies

(see standard IEC 62040-3, Annex B for details):Stand-by (off-line):

The simplest concept.

The supply voltage goes from the input directly to the output. When input voltage is lost, output switches to the battery-powered inverter

(by

electro-mechanical switch (relay) or electronic switch). There is some switching delay. Line-interactive: An improved concept, used for smaller levels of power. It can stabilize the output voltage step by step so that it is as close as possible to the nominal value. When input voltage is lost, the output voltage is switched to the voltage from the battery-powered inverter.There is a small switching delay. Double-conversion (on-line): This is the most advanced type of UPS, used for a wide range of power levels. The input voltage is rectified by a rectifier and then changed by the inverter to the output voltage. This eliminates input voltage fluctuations and prevents interference transmission.The output from the battery inverter is connected to the DC link of the rectifier. When input voltage is lost, the inverter is immediately powered from batteries. There is practically no delay in switching to battery operation.The xSpider programme allows to solve only double-conversion (on-line) UPS.

xSpider – UPS integrationUPS - introduction

UPS operation modes

(double-conversion (on-line) UPS):Normal mode

(called

Mains

operation state in xSpider)

The mains power is rectified, and a clean sinusoidal voltage is created for critical loads. The inverter filtering all disturbances from mains voltage.Stored energy mode (called Battery operation state in xSpider)The mains supply is not available.Inverter still provides continuous power for critical loads, but energy comes from the UPS system energy storage devices, typically batteries.Bypass mode (called Bypass operation state in xSpider)In cases the inverter is unable to provide power for critical load the UPS will transfer to bypass mode (due to overload or fault in the UPS or in downstream distribution).The static bypass is used as a redundant power path for the inverter.The maintenance bypass allows servicing of the UPS without load interruption, and it can be internal or external to a UPS.Note: Static bypass and maintenance bypass are not differentiated in the xSpider programme. From the point of view of calculation, their behavior is the same.Note: the operation state of the entire network is determined not only by the operation mode of the UPS, but also by the operation state of other

switching devices in the network.

Slide7

xSpider – UPS integrationUPS - introduction

UPS feed styles

(double-conversion (on-line) UPS):Dual feed

Connection of the UPS via separate lines for the rectifier and static bypass

Single feed

UPS connection via one common line for the rectifier and static bypass

Single feed is the cheapest way of creating the installation but may compromise its reliability

Note: in the xSpider programme feed style is set as property in Property grid.Dual feed

Single feed

Operation state manager:

Network must be checked in all operational states.

Operation state manager enables to define

which switching devices will be on or off,

motor state (start or steady state),

UPS (mains or bypass or battery).

Operation state manager enables to switch between states quickly. There should be minimally 4 operation states to explore:UPS in “Mains” operation state (normal state of network);UPS in “Bypass” operation state;UPS in “Battery” operation state;UPS maintenance (UPS fully isolated maintenance bypass outside of UPS connected).

IccInput and Icw ≤ IcwInput , otherwise error appears;Short circuit at UPS bypass terminals: Ik’’ ≤ IccBypass and Icw ≤ IcwBypass , otherwise error appears.UPS in “Mains” and “Battery” operation states – short circuit current behind UPS is calculated from invertor time-current characteristic. Peak values (ip3p, ip1p) are not displayed in whole network (info text is displayed). Simulation of the automatic switching from “Mains” to “Bypass” is not available in xSpider yet (info text is displayed).UPS in “Bypass” operation state – short circuit current from source is transferred through UPS (impedance of bypass is negligible).Sometimes fuse is required in bypass branch.This calculation must be repeated for maintenance bypass (outside UPS) operation state (because of short circuit is transferred through).

Short circuit at UPS input terminals:

Ik

’’ ≤ IccInput and Icw ≤ IcwInput , otherwise error appears;Short circuit at UPS bypass terminals: Ik’’ ≤ IccBypass and Icw ≤ IcwBypass , otherwise error appears.UPS in “Mains” and “Battery” operation states – short circuit current behind UPS is calculated from invertor time-current characteristic. Peak values (ip3p, ip1p) are not displayed in whole network (info text is displayed).Errors at protective devices behind UPS may appear. These errors can be omitted because UPS itself clear short circuit in short time (up to 0.4s); this fact is mentioned in error messages.Simulation of the automatic switching from “Mains” to “Bypass” is not available in xSpider yet (info text is displayed).UPS in “Bypass” operation state – short circuit current from source is transferred through UPS (impedance of bypass is negligible).

Short circuit must be disconnected by protective devices in requested time. Sometimes fuse is required in bypass branch.This calculation must be repeated for maintenance bypass (outside UPS) operation state (because of short circuit is transferred through and must be disconnected by protective devices in requested time).

UPS integration

Time-Current characteristic:

Tripping characteristic module enables compare UPS time-current characteristic with tripping characteristic of any protective device in wiring diagram.

Release setting of protective device can be adjusted to get selectivity.

Can be use also without wiring diagram drawing (Curve –Select mode).

Tip: use separate tripping chars collection for input, for output and for bypass.
