Design of Electrical EHT and HT Transmission, Distribution Systems and Sub Stations. Electrical Engineering Consulting Firms
Electrical high tension (HT) and extra high tension (EHT) transmission systems are used to transmit electrical power over long distances, typically from a power plant to substations that are located near end-use customers. These transmission systems operate at very high voltages, typically in the range of 115 kV to 765 kV, in order to reduce electrical losses during transmission.
The design of HT and EHT transmission systems involves several key considerations, including the selection of transmission line configurations and tower designs, the protection and control of the transmission system, and the design of substations.
Transmission line configurations and tower designs:
Transmission lines are typically designed using either overhead lines or underground cables. Overhead lines consist of a conductor (usually made of aluminum or copper) supported by towers or poles, while underground cables are buried in the ground. Each type of transmission line has its own set of advantages and disadvantages, and the selection of the appropriate transmission line configuration will depend on factors such as the distance to be covered, the terrain, and the available right-of-way.
The design of transmission towers or poles is an important aspect of the transmission system, as they must be able to withstand the forces exerted by the transmission lines, as well as environmental conditions such as wind, ice, and earthquakes. Transmission towers or poles are typically made of steel, and are designed using structural analysis tools such as finite element analysis (FEA).
Protection and control of the transmission system:
The protection and control of the transmission system is critical for ensuring the reliability and stability of the power grid. Protection systems are used to detect and isolate faulted sections of the transmission system, while control systems are used to regulate the flow of power and maintain the voltage and frequency of the transmission system within acceptable limits.
Protection systems typically use sensors and relays to detect abnormal conditions on the transmission system, and to initiate appropriate protective actions such as circuit breaker tripping. Control systems may use a variety of devices such as transformers, capacitors, and reactive power compensators to regulate the flow of power and maintain the voltage and frequency of the transmission system.
Design of substations:
Substations are an important part of the transmission system, as they are used to transform the high voltage electricity transmitted by the transmission lines to lower voltage levels suitable for distribution to end-use customers. Substations are also used to switch power between different transmission lines, and to connect generators, loads, and transmission lines.
The design of substations involves the selection of appropriate transformers and switchgear, as well as the layout of the substation to ensure the safety of personnel and equipment. The substation layout may include facilities such as control rooms, transformers, switchgear, and protective equipment.
Design of Auto synchronizing and Auto load sharing of large substation DG sets. Electrical Engineering Consulting Firms
The design of an automatic synchronizing and load sharing system for large substation diesel generator (DG) sets involves several key considerations. These include the selection of appropriate control systems, the design of the power distribution system, and the selection of protective devices to ensure the safe and reliable operation of the DG sets.
Control systems:
The control system is an important part of the automatic synchronizing and load sharing system, as it is responsible for coordinating the operation of the DG sets and controlling the flow of power to the load. The control system typically includes a control panel, a synchronizing panel, and various sensors and control devices such as relays and timers.
The control panel is used to monitor the operation of the DG sets and to initiate the necessary control actions. The synchronizing panel is used to synchronize the frequency and phase of the DG sets with the power grid, and to transfer load between the DG sets as required.
Power distribution system:
The power distribution system is used to distribute the electrical power generated by the DG sets to the load. The distribution system typically includes a main distribution panel, distribution transformers, and distribution circuits.
The main distribution panel is used to distribute the electrical power generated by the DG sets to the distribution transformers, which step down the voltage to levels suitable for distribution to the load. The distribution circuits are used to distribute the power to the end-use customers.
Protective devices:
Protective devices are an important part of the automatic synchronizing and load sharing system, as they are used to ensure the safe and reliable operation of the DG sets. Protective devices may include circuit breakers, fuses, and relays, which are used to protect the DG sets and the power distribution system from overcurrents, short circuits, and other abnormal conditions.
The selection of appropriate protective devices is an important aspect of the design of the automatic synchronizing and load sharing system, as they must be able to operate correctly and reliably under a wide range of operating conditions.
Design of substation automation with P.L.C. Controls Electrical Engineering Consulting Firms
The design of substation automation using programmable logic controller (PLC) controls involves several key considerations. These include the selection of appropriate PLC hardware and software, the development of control algorithms and logic, and the integration of the PLC system with the substation’s existing equipment and systems.
PLC hardware and software:
The selection of appropriate PLC hardware and software is an important aspect of the design of a substation automation system. The PLC hardware typically includes a central processing unit (CPU), input/output (I/O) modules, and communication interfaces. The CPU is responsible for executing the control algorithms and logic, while the I/O modules are used to interface with the substation’s equipment and sensors. The communication interfaces are used to connect the PLC system to other devices and systems such as SCADA (supervisory control and data acquisition) systems, human-machine interfaces (HMIs), and other PLCs.
The PLC software is used to program the control algorithms and logic that will be executed by the PLC system. PLC software typically includes a programming language, development tools, and a runtime environment. The programming language is used to write the control algorithms and logic, while the development tools and runtime environment are used to compile and execute the control programs.
Control algorithms and logic:
The control algorithms and logic are an important part of the substation automation system, as they determine the actions that the PLC system will take in response to various input signals and conditions. The control algorithms and logic may be developed using a variety of techniques, such as ladder logic, sequential function charts, or function block diagrams.
The control algorithms and logic should be designed to ensure the safe and reliable operation of the substation equipment and systems. This may involve the implementation of protective and safety functions, as well as the control of equipment such as transformers, switchgear, and protective devices.
Integration with existing equipment and systems:
The PLC system should be integrated with the substation’s existing equipment and systems in order to ensure the seamless operation of the automation system. This may involve the development of interfaces and protocols to connect the PLC system to the substation’s sensors, actuators, and other devices.
The integration of the PLC system with the substation’s existing systems may also involve the development of monitoring and control interfaces, such as HMIs or SCADA systems, which allow operators to monitor and control the substation’s equipment and systems.
