Abstract

An arhitecture for power distribution system, which comprises of three types (Power Sink, Power Distributor and Power Provider) of devices, is disclosed. Such architecture enables data communication between each other via PLC, and makes each component aware of the situation of the power network. Each of component sends out its consumption status, power specifications and unique identifying information to their neighbor nodes. Also, the Power Distributor and Power Provider gives out commands to the Power Sinks and enters alert mode when necessary, so as to keep the power network secure and healthy. Various scenarios that the architecture is applied to are disclosed as well.

A Load-aware Architeture for Power Distribution System

Currently we usually connect device(Server/Storage/Switch) to 2 PDUs to make them work with stable power provider, but there's no solution to automatically show which PDU is connected to which power unit of the device (for example we may put device's power plugs into the same PDU by mistake, and there's no function to defect such situation remotely/automatically).

Our invention offers a solution to make all power components (Power Provider, Power Distributor, Power Sink, etc) capable of offering information to other components, so that devices (Server) can detect the Power Provider situation (e.g. connected to 1 PDU when we planned to connect to 2) and generate report/alert accordingly.

And per the invention, a Power Distributor/ Power Provider can recognize how many devices are connected , so it can resolve below problems also:


1. Devices are not all ways running in the full load, so when they are connected to a Power Distributor, they have potential risk to make the power over charge. Per the invention, once a device is connected to a Power Distributor, the Power Distributor/Power Provider can count out that how many devices are connected and what the max power it may afford, so it can produce a warn if it can't afford the max power.


2. There maybe connection issues in electric wires which can cause power wasting. Per the invention the power provider can show the power it offered and the actually power used by devices (each device can report to PDU the volume of the power it uses) so that we can find if something goes wrong in the electric network.

The architect proposed here involved 3 parties in the power distributing system:

- Power Sink (power moves in and never move out, e.g. power unit of a server)

- Power Provider (power sources, e.g. UPS or transformer)

- Power Distributor (power moves in and out, e.g. PDU)

All three parties are connected by power cord with PLC communication enabled so that inter-communication is possible.

The Power Sink could send any or all of the following information:

- Current consumption status(current, voltage, frequency, power)

- Max/Peak/Rating power

- Manufacturer/Serial Number

The Power Distributor could send any or all of the following information:

- Current total consumption status(current, voltage, frequency, power)

- Number of connected Power Sinks / Power Distributor (e.g. hierarchy connection)

- Info of individual Power Sink / Power Distributor (per request)

- Manufacturer/Serial Number

- Commands to change setting of Power Sink

The Power Provider could send any or all of the following information:

- Status of Power Provider

- Request of retrieving info of an individual Power Sink / Power Distributor

- Commands to change setting of Power Sink

There are two major benefit in this architect:
1. The Power Sink will be aware of the source of its power. For example, the server with two power units (Power Sink) will know if...
