Energy Automation

Energy monitoring automation prepare the ground for attempts to keep the level of energy consumption at an optimal level by providing continuous monitoring, reporting and recording of the energy consumed in industrial plants. Faults related to boards in the system, circuit breakers, transformers, generators and similar systems are constantly monitored via energy analyzers and other monitoring devices. Processes to be executed for energy efficiency are identified according to data obtained for voltage, current, power factor, power, active-reactive energy, and the elements in the system are optimized.

Through remote access via online and mobile platforms, all data related to energy consumption can be monitored easily.

HPP and WPP Plants

Hydroelectric Power Plants

In hydroelectric power plant SCADA system; water level, temperature values, control of turbines, pressure and flow control are instantly monitored, reported and recorded in the database. PLC system runs with redundancy. System configuration is designed accordingly. Control of any information related to Intake gate, water level, oil level, temperature, pressure and speed is provided in automation of hydroelectric power plants. Turbines are instantly monitored and controlled. Synchronization of generators is provided. HV, MV and LV power distribution and command systems are controlled. From SCADA and mimic control desk, monitoring and control operations are carried out. Protection relays, regulators and the energy analyzers are monitored. Plant emergency stop scenarios are applied. On / off information is received for all valves and switches. Warning, synchronization and fault information is transmitted.

Wind Power Plants

Wind power plants are becoming more common in the context of renewable energy. In these systems, various parameters are monitored and controlled. All the components of the MV breakers, separators and soil separators for all turbines, step-down centers and the main distribution network cells are monitored and safely controlled. Any kind of measurement value, data, information, alarm and fault conditions are real-time monitored, reported and recorded in the database via SCADA system. Thanks to flexible reporting periods available on demand for all production process and amount of production, it is easier to make the right analysis and forecasts. Thanks to the remote monitoring of the plant through the Web interface, a flexible structure is obtained.

Energy Monitoring

With the energy monitoring system, simultaneous monitoring, reporting and control is provided for of all electrical values recorded over energy analyzers. Network-generator switching can be automated. Reports for many parameters including faults, operation and energy consumption can be produced at hourly, daily, monthly, or annual basis. Authorization levels for users can be defined so that different authorities are given to each operator and system security is provided. For transformers, signals such as Bucholz start, Buchholz alarm, temperature start, temperature alarm and oil level are monitored. Fuel tank levels and cooling unit of generators can be controlled. By connecting to the security systems like fire alarm, earthquake warning, or natural gas leakage, immediate power interruption can be ensured in case of any danger. Unloading and loading operations are performed.

All the electrical data such as UPS, LV distribution board, flows associated with transformer, voltage, power, frequency, power factor and harmonics can be traced by energy SCADA applications. Based on data from energy analyzers in the plant, generator relays, network relays; flow in the plant, voltage, frequency, active and passive energy and power monitoring can be done. They are shown graphically on the SCADA screen and saved to the database. Through remote access, all data can be monitored via online and mobile platforms. If the system is spread to a wide geographic area, a good communication RTU (Remote Terminal Unit) is used to record many active values in case of power outages.

Compensation

In practice, factories, electrical machinery, construction machinery and engines supply reactive power to the network they connect, as they work inductively. This reactive power causes considerable fall in active power, thus a fall in yield in return. When the same system is compared for uncompensated and compensated states, it is seen that the current drawn does not change, but there is an increase in the active power. A compensation board is connected to the entrance of the inductive system to increase work productivity and to prevent reactive power from affecting the network, so that the reactive power produced in the circuit has been stored in the condensers without going to the network. When the engine starts working, these condensers switch the reactive power they stored back to the engines. Therefore, the network recognizes the system close to a pure resistive one and no reactive power exchange happens between the network and system. Industrial plants with high electricity consumption, if exceed the specified capacitive value, are faced with raised electricity bills, and face losses caused by reactive loads. A well-designed compensation system can provide a saving of up to 25%.

Synchronization

Synchronous generators feed up the loads based on replacement working principle, on the basis of power analysis. Synchronization allows generators to activate and deactivate automatically according to power demand. Generators are used to ensure energy continuity and are expected to supply energy to the required level automatically. With the re-activation of the network, the system monitors the network instantly. A smooth transition of the load from the generator to the network is provided when the harmony between the parameters of generator and the network is achieved. Thus, the energy continuity is ensured. It is necessary to establish synchronization system, especially for diesel generators to enable parallel operation between them or between generators and network.
