LOAD MANAGEMENT AND AUTOMATED DISTRIBUTION
This section sets forth RTU equipment specifications to support Load Management and
Automated Distribution capabilities utilizing Power Line Carrier Communications for
control of subscribers’ loads and for system control, data collection and metering.
4.1
System Description
The Load Management and Automated Distribution Equipment specified shall be
furnished as part of the RTU and shall consist of the necessary injection and primary
coupling equipment for coupling to one (1) substation bus.
The main components of the system shall consist of a Carrier Control Unit (CCU), a
Signal Coupling Unit (SCU), and a Primary Coupling Assembly (PCA). The Load
Management and Automated Distribution System shall provide for one-way and bidirectional communications utilizing distribution line carrier (DLC) technology. For oneway functions, the central station will originate communications to the carrier control unit
located in the substation. The central station computer to carrier control unit
communication channel will be by IP over fiber.
S-6
Schedule VII
The carrier control unit, located in the substation, shall receive the central station
communication, decode the address to determine if the communication is addressed to it,
check the communication for accuracy, reformat the communication to the DLC protocol
and transmit the communication via coax cable to the signal coupling unit (SCU). The
signal from the signal coupling unit shall be coupled to the distribution substation bus
through a three-phase primary coupling assembly consisting of three single-phase
distribution transformers which will be furnished under a separate schedule and are not
included in these specifications.
Once the carrier signal is coupled to the distribution substation bus, it will propagate out
all feeders to the load management terminals installed at user locations. The load
management terminals shall receive the carrier communication directly from the service
wiring, determine if they belong to the group being controlled, and performed the
requested load control function.
When bi-directional communication is utilized for automated distribution functions, the
communication path to the remote terminal will be identical as with a one-way command.
The remote terminal units shall receive the signal and decode it to determine if it contains
their unique address. If the communication is directed to the terminal, the
communication shall be checked for accuracy, the required command function performed
and a return signal transmitted back over the distribution feeder via carrier. This carrier
signal shall be decoupled at the substation by the primary coupling assembly and sent
through the SCU to the carrier control unit. The carrier control unit shall check the
received signal for accuracy, reformat the protocol and transmits it to the central station
computer.
Each bidder shall include as part of his proposal, a complete description of the system
which he proposes to furnish. The description shall include hardware, future hardware
requirements, operating strategies, significant parameters, points of flexibility, data
collection capability, and control implementation. In particular, the editing required to reassign load control switches between control groups shall be described.
4.2
Carrier Communications Unit (CCU)
The carrier communications unit shall be capable of receiving, translating and
retransmitting the commands from the Central Station. Commands and data messages for
communications in either direction shall be transmitted over private, voice grade
communication lines. The CCU shall format these messages for distribution line carrier
transmission at the appropriate frequency. The message shall be amplified by the CCU
and coupled to the distribution lines by a Primary Coupling Assembly for transmission to
S-7
Schedule VII
the end use terminals. The CCU shall be capable of two-way communications and shall
receive reply messages from terminals over the same distribution lines and shall format
these messages for compatibility with the Central Station. The CCU shall monitor the
quality, accuracy, and completeness of the message communication using the parity
confirmation and BCH error checking techniques. All transmit switching shall be done at
zero power levels to enhance the reliability of the CCU by extending the life of the CCU
relays.
4.3
Signal Coupling Unit (SCU)
The capacitive signal coupling unit (SCU) shall be adjustable to tune the impedance of
the SCU to that of the substation bus and primary coupling assembly to provide for
maximum signal transfer. Signal coupling units shall be furnished with surge protection
and shall operate at the carrier frequency. Signal coupling shall operate in a temperature
range of -40 degrees C to +55 degrees C and a relative humidity of 0 to 100% noncondensing.
5.
SPARE PARTS
No spare parts are required with this RTU.
6.

deficiencies and effective corrective action. The complete process shall result in
documented test reports which confirm that all components and functions are thoroughly
tested in a methodical and organized manner in accordance with a written test procedure.
7.1 Factory Acceptance Test
The purpose of the Factory Acceptance Test is to demonstrate that the hardware,
software, and documentation to be delivered shall meet or exceeds the contract
requirements.
