Gia Lai Power Company: implementation of solutions to reduction of grid faults
The roadmap for enhancing reliability in power supply, for minimizing grid faults of EVNCPC in general or Gia Lai Power Company (PC) in particular, is being implemented with many requirements. This is the reason that Gia Lai PC held the Conference for solutions to reduction of grid faults taking place on 03 June 2019 with participation of the PC’s leader board, its subsidiaries and staff.
Gia Lai PC held the Conference for solutions to reduction of grid faults
According to summary report of grid operation in the first five months of 2019, Gia Lai PC well performed its task in supplying power for socio-economic development of Gia Lai province. The maximal power reached 252MW, increasing by 25MW as compared to counterpart period of 2018. The peak of daily power sales reached 4,474,806 kWh, increasing by 414,416kWh (+10.2%) as compared to counterpart period of 2018. Since the beginning of this year, in Gia Lai province, there have been 489 outage cases due to grid faults and handling of MV/LV grid faults, which causes an average of 110 minutes of power outage/customer, reducing 245 cases as compared to counterpart period of 2018.
At the Conference, reasons of grid faults were scrutinized in order to propose proper solutions. Accordingly, the main reasons are lightning, violation of safety distance, animal, faults from customer side and some other reasons. In which, lightning takes up the largest proportion: 149/489 cases, equivalent to 30.74%. The reason is that Gia Lai province is situated in highland, monsoon, tropical climate with high humidity, its rainy season lasts from May to November with large precipitation ranging from 1,200-2,500mm. Most of power line routes go through unfavorable areas such as: mountains, forests… in addition to that, at the beginning of rainy season, the province experiences not only a high concentration of lightning but also other unfavorable weather conditions: fog, humid climate… which results in lightning faults on power line and substation.
Mr. Thai Dinh Thy – Manager of Pleiku Power Branch presenting his topic at the conference: Solution to reduction of grid fault due to lightning and unfavorable weather conditions
From the above-mentioned reasons, delegates presented topics and initiatives on solutions to accomplishment of tasks to reduce grid faults in 2019. In which, there are pre-eminent topics: Solution to reduction of grid faults due to lightning, unfavorable weather from Pleiku Power Branch; Solution to reduction of grid faults due to violation of safety distance from Duc Co Power Branch; Solution to reduction of grid faults due to animals from Chu Prong Power Branch, Solution to reduction of faults on customer grid from Ia Grai Power Branch and Solution to reduction of 110kV grid faults from 110kV grid operation team.
With the target of 2019 issued by Vietnam Electricity (EVN): “Enhancement of efficiency in power system operation and power market” and in order to meet power demand for socio-economic development of the country; to ensure optimal operation of power source, power system; to meet power demand for socio-economic development of Gia Lai province and for daily activities of the local people, Gia Lai PC has been striving to complete all the missions, economic-technical targets and customer-satisfaction goal assigned by EVNCPC, in which, to continue to further the task for reduction of grid faults, in order to prevent power outage and to improve the reliability in power supply toward customers, is one of the missions.
