Easing the energy crisis with efficient hydro powerIntegrated, flexible architecture for all your generation installations

As regulators impose clean electricity targets from sustainable generation, electricity producers

focus on stable renewables such as hydro power. As the most widely used

energy source available today and with power plants ranging from less than one to

more than 100 megawatts, hydro production is considered as a flexible and reliable mainstream

renewable source.

The expected annual increase in total energy generation from renewable sources.

Hydro Power Generation • 03

Improving the performance of small hydro plantsBetween those two extremes is the small

power plant, which ranges from 1 to 30

megawatts. Operators of these plants are

constantly striving to improve performance

and to guarantee security for both plant

processes and the people working there,

but additionally they need to:

• Minimise system failures and

ensure high availability

• Maintain the right levels of

power quality

• Reduce their investment and

operating costs

Meanwhile, improving operational energy

efficiency and reducing the environmental

impacts are also important considerations.

What plant operators really need is an

integrated solution that reliably and

consistently addresses all of their concerns.

Flexible, efficient solutions with higher availabilitySchneider Electric™ offers precisely that:

a complete power and control solution

for hydro power plants, built to enable

higher availability as well as multi-site

management, remote maintenance

and diagnostics.

We provide solutions specifically tailored to

the specific needs of all hydro power plants,

whatever their size, ensuring that each is:

• Scaleable and modular

• Flexible and based on

world-class products

• Easy to use, integrate, operate,

and maintain

• Built to enable high availability

Driving performance with simplicity and integrated functionsThe Modicon M340 from Schneider Electric PlantStruxure™ architecture

As part of PlantStruxure architecture,

our Modicon programmable automation

controllers (PACs) are far more than a PLC

and are built to suit the specific needs of the

hydro power industry. Modicon M340 can

be used individually, but is also the perfect

companion of both Modicon Premium and

Modicon Quantum, increasing the quality and

profitability of power generation processes and

overall plant performance.

An adaptable architecture with multi-unit controlSmall hydro power plants are equipped

with several turbine-generator units, which

are not all the same. Taking this into account,

Modicon M340 architecture allows specific

control of each turbine-generator unit,

thus ensuring the turbine speed is

managed efficiently according to the

turbine power curve.

Increase your availability with advanced PLCs Modicon Premium or Quantum PLCs are

perfectly adapted for hot standby architecture

and can bring increased performance to

complex applications.

The Modicon M340 is compact, flexible,

and well-suited to harsh environments,

allowing incident-free operations between

-40C and +70C. With a high degree of

reliability and stability, these PLCs offer

remarkable calculation and permutation

performance, and are always ready to take

control with total transparency.

PlantStruxure solutions give hydro power plants the efficiency they deserve, by:

• Providing a high availability architecture

that reduces the amount of unplanned

downtime in your process

• Integrating production data with other

business systems to improve your

production scheduling

• Reducing engineering, operating and

maintenance costs

• Delivering real-time business information

and ensures that you have access to your

process and production data, anytime and

anywhere

Open, flexible architecture for managing multiple sitesA reliable SCADA system with Schneider Electric PlantStruxure architecture that improves operational reliability

Because plant operators need both

central and remote management of

different hydro power plants, our SCADA

system is completely capable of supervising

multiple remote stations and minimising

process downtime.

Using a redundant server, clients and

communication, we provide intelligent

integration with the existing information

system, including the data archive,

historical trends, reports, and alarms.

Additionally, our management solution:

• Is multi-level and easy to configure

• Enables real-time remote monitoring

• Seamlessly incorporates third-party

software

• Is flexible and scaleable for

future development

Configuration and maintenance of the system

is both simple and secure, reducing your

operational expenses and providing greater

visibility into your multi-site network.
