This presentation covers the following areas

The Hong Kong 1980 Grid Coordinate System • Hong Kong is a small area. Its coverage is about 70km by 45km. • A plane rectangular coordinate system is most suitable for describing position. – it is convenient for plotting a point on a plan. – easy to calculate the distance and direction between two points using simple coordinate geometry.

The Metric Coordinate System 1980. Red Point = Origin. In 1970s, the metrication policy was executed in Hong Kong, the Imperial grid was converted to metric unit of measure in 1975-77 with the grid origin (zero origin) further shifted 3550 meters to the west. That means, Northing + 800,000m and Easting +800,000m and reduce 3550m in value.(1

How many kV power lines does Hong Kong Island have?

HEC transmits electricity on Hong Kong Island at 275 kV and 132 kV voltage level to various load centres, in which the network consists mainly of underground and submarine cable. The network is owned and operated by HEC. There are only few remaining 132 kV overhead power lines in the system.

Who owns the Hong Kong electricity network?

The network is owned and operated by HEC. There are only few remaining 132 kV overhead power lines in the system. The use of underground cable was chosen because it is ideal for a densely populated area like Hong Kong, and to ensure supply reliability even in bad weather, such as during typhoon.

Who provides electricity in Hong Kong?

There are two main providers of electricity in Hong Kong. Power generation in Hong Kong is managed by two major companies under a Scheme of Control arrangement with the Hong Kong Government. These companies effectively operate in a regulated market.

What are the benefits of grid connection for user-constructed re power generation system?

For a grid-connected system which is connected to the electrical distribution system of the site, the power flow from the utility grid will compensate for the fluctuation in the power output of the RE power generation system. In summary, the benefits of grid connection for user-constructed RE power generation system are:
