P00625 – Periodic Supply and Delivery of Voltage regulators

The Organisation

Western Power is a Western Australian State Government owned corporation responsible for building, maintaining and operating an electricity network that connects our 2.3 million customers to traditional and renewable energy sources, delivering an essential service to our community.

The Scope

Western Power is seeking registrations of interest from suitably qualified and experienced organisations, for the provision of Single Phase Voltage Regulators to be suitable for use on the Western Power 33kV/19.1kV, and 22kV/12.7kV, AC distribution systems throughout the State of Western Australia, in conditions where a wide range of solar radiation, pollution (salt bearing) and wind velocities are experienced. Single Phase Voltage Regulators are required for pole mounted and for ground mounted (inverted culvert) situations. 

The overriding functional requirements for the Voltage Regulators are: 

1. They must provide safe and secure operation, ensuring minimal risk to the public.
2. There must be safe access for inspection and maintenance by operational personal.
3. They must provide the network with consistent voltage adjustments consistent with the settings applied. 

In addition, the following functional requirements are applicable: 

a) The primary function of the Voltage Regulator in the various sizes is to boost its incoming voltage and provide an outgoing voltage adjustable by +/- 10% in 0.625% increments as the minimum performance rating. Incoming voltage may be applied to both sides of the Voltage Regulator, and are required to handle Reverse Power Flow.

b) All primary Voltage Regulators shall operate at 50 Hz and be suitable for outdoor use.

c) All Voltage Regulators, shall be communication ready and where possible, shall be DNP3 compatible.

d) All Voltage Regulators shall be designed to eliminate attacks and impact from cockatoos, rodents, reptiles and other animals, as far as is reasonably practicable.

e) All Voltage Regulators shall be designed and supplied with consideration of the potential impacts to the environment, to be as low as reasonably practicable, particularly with respect to containment of:

1. hazardous materials.
2.  noise.
3. chemical emissions.
4. protection of biodiversity. 

f) All Voltage Regulators shall be permanently marked for easy identification, i.e. equipped with a name / rating plate that complies with AS 60076.1. 

While Western Power traditionally use open bushing Voltage Regulators, we request proposals with elbow/boot connectors to provide improved safety and environmental performance. 

Registration Requirements
