SCADA Power Distribution Solution (SCADA PDS ) introduction

VINSYS Smart Power Distribution Solution (SCADA PDS)

The difficulties in managing low-power grid

In Vietnam, a local power companies operates from 50 to 100 low-power electric cabinets. Those cabinets are distributed in an area having range from 5 to 11 kilometers. In each cabinet there are power meters (PM) to measure data such as U, I, P, Q.

Some difficulties in managing low-power grid:

– There are a lot of distributed electric cabinets but workers are managing them manually. They have to go onsite to control the circuit-breaker in each cabinet.

– Operators at SCADA center don’t know which cabinet are having power-off state because there has not been any way to monitor cabinets in real-time.

– It is difficult to make end-of-month detail reports about the operation of the grid because the information is on hand-books of many workers.

Those difficulties lead us to develop SCADA PDS solution

System benefits
