Quang Nam Power Company: Comprehensive change to adapt

Over 23 years of establishment (1.4.1997 – 1.4.2020), with investment solutions to modernize technical infrastructure, apply advanced management systems, improve human resources, and quality of electricity supply and customer service, Quang Nam Power Company (PC Quang Nam) is aiming to invest in building a smart grid to adapt to changes of the 4.0 technology revolution.

Smart grid investment

Following the orientation of the Central Power Corporation (EVNCPC), Quang Nam PC is focused on investing in building a smart grid to adapt to the change of technology revolution 4.0, with a focus on building the center remote control and substation (TBA) without personnel to soon put into operation.

Previously, the function of remote control and monitoring of TBAs was limited to simple manipulations such as switching and switching machines, the rest of other operations were performed manually on the device. Meaning that the equipment is asynchronous, there is no integrated system of information and general alarm handling, but now it relies on the remote control center, the control staff handle and operate by integrated control systems computers, improving the capacity of professional and professional operators, computer handling, manipulation skills, reducing operating costs, etc. The management and operation of non-duty TBAs is the solution. optimal solution for electrical system control in the province today.

Up to now, Quang Nam PC has had 11 110kV TBAs switched to non-duty operation mode. As a result, timely monitoring and adjustment of grid operation parameters, reducing equipment operation time, quickly handling incidents, contributing to increase labor productivity and improve production efficiency. business and customer satisfaction using electricity.

Quang Nam PC is managing a fairly large and synchronous grid volume, including 13 TBA of 110kV source, more than 270km of 110kV lines, more than 8,842km of medium and low voltage line and 3,815 TBA of additional charge. In recent years, Quang Nam PC has always focused on investing in research and application of modern technology to upgrade and modernize the electricity grid, contributing to improving the reliability of electricity supply.

Quang Nam PC has also successfully applied hot electricity repair technology on the grid such as connecting, repairing, cleaning of existing lines, not cutting electricity – which means not interrupting the production process, people’s activities. Application of grid management software of GIS technology; technical management of power sources and electrical grids; enterprise human resource management system… have brought high economic efficiency.

Ending in 2019 – considered a major event of the unit in 23 years of construction and development, by Quang Nam PC has provided electricity output exceeding 2 billion kWh / year. All economic – technical indicators, production and business activities have met and exceeded the plan.

The “transformation” steps of Quang Nam PC are contributing to bringing electrical services asymptotic to customers, helping people in the area to conveniently and quickly use services wherever they are, at any time, always trusted by customers. With these efforts, the customer satisfaction score has increased year by year.

After 6 years (2013-2019), continuously performing the average customer satisfaction survey for PC Quang Nam increased from 6.33 points in 2013 to 7.87 in 2017 and in 2019 reached 8 points.

Priority for focus area

2020 is an important “sprint” year in the process of implementing the 5-year plan from 2016 to 2020, Quang Nam PC is aggressively deploying synchronous solutions to invest in upgrading the power grid, especially the construction of the grid smart electricity, aiming to perfect modern power grid according to the policy of the industry.

With the motto “electricity is one step ahead” to create momentum for economic growth, Quang Nam PC pays special attention to investment, improving the grid system, contributing significantly to attracting investors to in the field of industrial production as well as meeting the need to increase capacity, expand production in tourist areas and industrial parks in the eastern region of the province.

Accordingly, PC Quang Nam is continuing to focus investment in overloaded areas; increase investment in equipment to connect remote control nets; to consolidate the western mountainous electricity grid in Quang Nam, to supply new large loads for investment in the Eastern region and Chu Lai open economic zone. In 2020, it will focus on investing in new towing, renovating and raising the capacity of 258 TBA; renovate and build more than 218km of low voltage lines, more than 126km of medium voltage lines (22kV, 35kV) with a total investment of more than 234.2 billion VND.

Regarding overhaul, Quang Nam PC will renovate 33 TBAs with 156.6km of low voltage lines, 225.6km of medium voltage lines and 1.5km of 110kV lines with a total capital of more than 112.4 billion VND. Along with Quang Nam PC, EVNCPC is also implementing key projects in the province such as investing in network improvement in 4 localities Nui Thanh, Dien Ban, Tam Ky and Hoi A; build and connect after the 220kV Duy Xuyen station, the 110kV Duy Xuyen – Hoi A line; raising the capacity of Tam Ky 110kV TBA, with a total capital of over 410 billion VND.

The projects are invested with the goal of meeting the load development needs, improving the reliability of power supply and adding medium voltage networks to close the loop, installing the circuit breaker, Recloser, etc., step by step completing the structure. Distributed grid structure, meeting N-1 standards, paving the way for smart grid development.

Mr. Nguyen Minh Tuan – Director of Quang Nam PC said that in the coming years, Quang Nam PC will focus resources and capital to develop infrastructure grid, meeting the power demand for key projects in the southeast region of the province is forecasted to have a rapid growth rate. Therefore, it is required to soon invest in the station system and source grid, especially to expand the 110kV, 35kV substations, etc., to prepare for the investment capital inflow here.
