Overview

The PDR-2000 is a digital protective relaying teleprotection terminal used for high speed tripping communications in pilot protection schemes for electric power transmission and generation. The PDR-2000 is capable of transmitting and receiving up to 8 channels over serial digital communications, fiber optics, or four wire audio.

The PDR-2000 has two communication ports, allowing the unit to simultaneously operate over two digital communication lines. To increase security, each digital packet includes a Unit identification (ID) number. Packet Forwarding allows a PDR-2000 to communicate with units that are not directly connected as in a string or loop configuration.

Programmability

The PDR-2000 can be programmed using the keypad on the front panel or by using our Windows® based GUI (graphical user interface). Since no external programming equipment is required, field installation is easy.

Diagnostics & Testing

The PDR-2000 has advanced diagnostics using a fully featured event recorder. The event recorder can hold up to 40,000 events, after which the events are overwritten. Events are timed stamped by the internal clock which can be updated using an IRIG-B signal from a GPS clock and stored in Flash memory.

The same Windows® based GUI that is used to program the unit’s settings also accesses events. The GUI allows the user to download up to 1,000 events, which can be sorted by type, date and time. The keypad and display can also access events by starting with the most recent event and scrolling back chronologically.

Modules

Standard Modules

MICROPROCESSOR MODULE

The Microprocessor (uP) Module monitors and controls all trip inputs/outputs, communications, system status, and event recording. A real time clock with battery backup also resides on the uP Module. The PDR-2000 requires at least one uP Module but a second module can be installed in the same chassis for redundancy.

COMMUNICATIONS MODULE

The Com Module converts the received data from the uP Module to the desired communications protocol, and then sends the converted data to the com ports on the back of the terminal. The Com Module currently comes in five formats: RS-422, G.703, V.35, fiber optic or audio communications. Each Com Module type must be used in conjunction with matching com ports.

RS-232 MODULE

The RS-232 Module converts the asynchronous signal from the uP Module to the RS-232 electrical standard allowing the PDR-2000 to be interrogated for programming and event retrieval. The module contains a 9 pin DCE port on the front for connection to a PC for local programming and a 9 pin DTE port on the rear which allows remote access via a modem. The RS-232 Module also converts the IRIG-B signal input from the BNC connector on the rear of the chassis to a digital format before passing the signal to the uP Module.

DC/DC MODULE

The DC/DC Module contains redundant power supplies, fuses and voltage protection for the PDR-2000. The DC/DC Module provides DC power conditioning from the station battery input and from the DC converter input. The module is capable of handling up to two DC inputs that can be the same or different voltages. The DC Module has two status relays whose contacts close in case of power failure.

STATUS RELAY MODULE

The Status Relay Module contains eight relays which are used to notify external equipment when a change in system status is detected. The eight relays consist of (1) Alarm, (1) Block, (2) Loss of Communications, (2) Programmable, (1) Microprocessor Fail, and (1) Unit ID Off. All relays have jumpers to change the contact wiring from a form A to a form B and six of the relays can be delayed via programming.

TRIP IN MODULE

The Trip In Module communicates detected trips with the uP Module. The module contains eight optically isolated trip input circuits.

TRIP OUT MODULE

The Trip Out Module contains eight solid state relays for driving trip output circuits external to the unit or optional dry contact relays in the unit. The PDR-2000 can support up to two Trip Out Modules in a chassis.

Optional Modules

UNIVERSAL RELAY MODULE

The Universal Relay Module contains up to four mechanical relays that can be used for Trip or Guard indications. Each relay is a form "C" relay with a contact rating of 10A @ 24VDC or 3A @ 125VDC.

HEAVY DUTY RELAY MODULE

The Heavy Duty Relay Module contains four dry contact relays that can be used for trip outputs. Each relay is a form A relay with a contact rating of 10A at 125VDC continuous or 30A at 25VDC for less then 200ms. The Heavy Duty Relay Module may also be supplied without relays and serve as a Solid State Pass Through Module. In this form, if a Trip Out Module is placed in the optional slot and the solid state relays are not being used to drive the dry contacts, then the Pass Through Module allows the solid states to be wired to the terminal blocks,

CUT-OUT SWITCH MODULE

The Cut-Out Switch Module is used to provide an air gap isolation between the trip inputs and outputs, and the terminal blocks on the back of the chassis. A contact on the switch also acts as a status relay and may be configured as normally open or normally closed.
