TropOS wireless communication to two Hitachi

Energy TRIO PV inverters in order to coordinate

the power production according to the actual

conditions in the grid.

• Implemented voltage control substantially

improves the power quality in the grid.

• The local LVR control results in the desired

decrease of voltage in the “downstream” grid

branches independent of the end-customers

behavior and is fully under control of the grid

Cybersecurity: National grid operator in Northern Europe

37

Hitachi Energy’s customer is a

national grid operator in

Northern Europe controlling

15,000 kms of power lines,

160 substations, switching

stations and 16 overseas

power connections.

Customer’s challenge was that

they didn’t have the ownership

of the substation buildings and

therefore control of the

physical access was not in

their hands.

The national power utility of

Zambia, ZESCO, took the

chance to upgrade their

installed RTU211 to the new

RTU511. The customer

wanted to profit from the

functionalities of high-end

RTUs while keeping the

significant number of installed

RTU211.

Water : Turkey Irrigation Project

45

Korkuteli is typical; until the

1960s the lowlands were

home to sheep and goat

herders as the otherwise-

fertile ground were too dry for

growing crops, but with proper

irrigation, farmers are now

growing fruits, grain, and

vegetable oils, thanks to a

network of open canals. Those

canals are getting old now,

and suffer from leakage into

the soil as well as evaporation,

so the General Directorate of

State Hydraulic works decided

to rebuild the network
