DECIDES:
Article 1. Approving electricity planning of Hai Phong city
during 2016 – 2025 with an orientation towards 2035 – Planning for 110 kV
system
1.
Development orientations
a) General
orientations
- Development
the transmission and distribution grid together with socio-economic development
in each area and sub-area therein, ensure increasing quality and reliability of
electricity.
- Ensure that
the development of the transmission grid matches that of power plants in order
to achieve overall efficiency of the national and local electricity systems;
suitable for the electricity industry development strategy, electricity
planning and other planning of the area and sub-areas therein.
- Build
transmission lines suitable for long-term development. Ensure the grid meets of
N-1 standards for reliability, the structure of the grid ensures high
flexibility of management and operation. Carry out modernization and
undergrounding at tourist attractions, industrial parks and urban areas in the
city; minimize negative effects on the landscape and the environment. Improve
stability, reliability of power supply and minimize power loss. Ensure
effective and economic use of electricity; attract investment in projects that
have modern and energy-saving technologies.
- Improve
power supply reliability; apply technological advances and smart grids in grid
operation: (i) develop and complete SCADA system; (ii) Organize remote control
centers; build unmanned substations; (iii) Develop electronic meters and a
system for remote collection of power consumption data; (iv) Build a smart grid
system that facilitates interaction between the supplier and clients; (v) Apply
advanced technologies such as: large-scale monitoring system, transmission line
temperature monitoring system, system for fault detection, live-line working of
electrical and compensating devices.
-
Medium-voltage (MV) grid of the city is 22 kV. The 10 kV grid will be upgraded
to 22 kV by 2020. During 2021 - 2025, the 35 kV grid will be used in Do Son,
Hong Bang, Kien An district; 22 kV grid will be used in Kien Thuy and An Duong
district. The 35 kV grid in other areas will be changed to 22 kV in later
periods. Build underground cable systems in urban districts, towns of suburban
districts, new residential areas, industrial parks, etc.; gradually replacing
existing overhead lines in urban districts and towns of suburban districts with
underground cables to preserve urban landscape.

- Structure:
the design of 220 kV and 110 kV grids shall ensure reliability and quality of
electricity throughout their normal operation and in case of separate faults
according to applicable regulations. The 220 kV and 110 kV grids shall ensure
backups for development during next periods.
- 220 kV and
110 kV lines:
+ The design
of 220 kV and 110 kV grids shall ensure that each 220 kV or 110 kV substation
is supplied from at least 02 power sources (possibly from 2 busbar sections of
the same power plant or a 500 kV or 220 kV substation)
+ Consider
using compact poles for 220 kV and 110 kV lines or use underground 220 kV
cables in downtown areas of cities of Class II or above to preserve urban
landscape and meet power supply safety standards.
+
Cross-sectional area of cables: for overhead 220 kV lines, use multiple-phrase
cables that with a cross-sectional area of ≥ 600 mm2 with
preparation for next periods; use cables with a cross-sectional area of ≥ 300
mm2 for 110 kV lines. The cross-sectional area of underground cables
shall satisfy the same standards for overhead cables.
- 220 kV and
110 kV substations:
+ Each 220 kV
or 110 kV substation shall have 2 – 4 transformers. The capacity of the
transformers shall satisfy N-1 standards in the heaviest load scenario of the local
grid.
+ The busbar
diagram on the 220 kV and 110 kV side of a 220 kV substation shall ensure
flexibility and can be divided into at least 2 sections without reducing local
power supply reliability.
+ 220 kV and
110 kV shall have adequate land area for installation of reactive power
compensation devices or Flexible AC transmission system (FACTS).
