A modern SCADA system (hardware and software) with specific characteristics for electrical substations is presented. This system leverages the newest technologies available and shows the correct way to implement them in order to have a precise and fault secure power grid. The technologies included in the system are: network time synchronization, network communication redundancy through different types of ring topologies, specific SCADA software for electrical substation. At the end there is a proof of concept through which the practical way of implemeting these 3 technologies together is highlighted.

This paper explains the necessity of implementing Operations Management Software (OMS) in SCADA systems, by highlighting the benefits of OMS in water and wastewater plants. The modern approach for implementing this kind of system in a Service Oriented Architecture (SOA) is also presented, with examples of existing systems.

A solution for better controlling the number of equipments which can be powered from photovoltaic panels is presented in this paper. A hardware and software system is used for acquiring environmental data. These data are then sent to a fuzzy logic software which decides the number of equipments that will be powered directly from the photovoltaic panels, with the rest beeing pluged into the national power grid. Different ways of implementing the fuzzy logic are discussed, depending on the specific requirements: less power used from the national grid or less switching actions.

Industrial logistics is a very dynamic field, which involves moving equipment, flexibility, but also precise timing and accurate actions. Monitoring and control systems based on ZigBee can be implemented without causing obstructions or delays in the logistics flow. This paper presents different experiments using the industrial ZigBee equipment (coordinator, router, slave, bridge, sniffer) on different topologies and configurations.The purpose of these experiments is to find optimal topologies and settings for the ZigBee equipment, so that the implemented applications will be able to deal with the industrial environment, in order to acquire and transmit data as accurately as possible without losses of information and without interfering with the logistics flow. These experiments should be considered before implementing a ZigBee application in an industrial environment.
