Conclusion:
Stopwatch (AMR) replaced the power supply
company staff enter a meter reading program, realize the automatic meter
reading.
From the power line communications in the
early days of the concentrated a stopwatch application to now, smart meter
industry has experienced a long developing process.
Today, power line communication technology
is widely used in micro inverter solar and other renewable
solar grid tie inverter
system, electric vehicles charging concentrator, smart grid, smart
meters, temperature controller, home automation, factory automation, street
light control and so on.
Smart Meters to today's smart grid
development is an important milestone in the history of the development of
power industry, many organizations and services to industrial group is working
on smart grid services general communication protocol, for example, open
electric meter project, Meters and More federation and PRIME industry alliance
(large European power supply company was set up, including the Enel /, Endesa
and Iberdrola, established purpose is promotion and maintenance after the
widespread use of on-site inspection of power line communication technology),
IEEE P1901.
2 (IEEE working group on new narrowband
power line communications within the organization) and the largest broadband
power line communication workgroup HomePlug alliance.
Shandong taian's first residents
distributed photovoltaic grid-connected power generation project
On June 4, 10 16 points, shandong TaiAnShi
DaiYueOu dawenkou town south west Zhang Chuanyang remote village home 3 kw
distributed grid photovoltaic power project successfully incorporated into
taian, as taian company successful accept the first residents distributed
grid-connected photovoltaic (pv) projects, marked the TaiAnShi distributed inphotovoltaic (pv) power project "into" the ordinary people.
On June 4, 10 16 points, shandong TaiAnShi
DaiYueOu dawenkou town south west Zhang Chuanyang remote village home 3 kw
distributed grid photovoltaic power project successfully incorporated into
taian, as taian company successful accept the first residents distributed
grid-connected photovoltaic (pv) projects, marked the TaiAnShi distributed in
photovoltaic (pv) power project "into" the ordinary people.
Zhang Chuanyang is a teacher of shandong
agricultural university, for the rural comprehensive utilization of solar
energy research, in his hometown of 12 pieces of polycrystalline panels
installed on the roof, interconnection capacity of 3 kw, given operating mode
for the "spontaneous for private use, electricity on the Internet",
annual output can reach 4300 KWH.
Company is in taian city, shandong
province, according to state grid corporation has issued for single and points
total installed capacity of less than 6 megawatts of power generation projects
give free online services and other related policies and the shandong electric
power group company distributed photovoltaic projects grid service management
regulations (try out) "and other rules and adhere to optimize the
structure of power grid, promote energy conservation and emission reduction,
construction of taian" happiness "as the objective, set up covering
accepts an application, the interconnection scheme formulated, hooked up to the
acceptance, power trading, and electricity contract agreed, grid scheduling and
coordination mechanism, comprehensive, all-round, whole process service for the
customer provide free on-site investigation, access system scheme
establishment, hooked up to the acceptance and efficient services.
