𝗛𝗼𝘄 𝘁𝗼 𝗣𝗲𝗿𝗳𝗼𝗿𝗺 𝗥𝗲𝗮𝗰𝘁𝗶𝘃𝗲 𝗣𝗼𝘄𝗲𝗿 𝗖𝗼𝗺𝗽𝗲𝗻𝘀𝗮𝘁𝗶𝗼𝗻? 🤔 The capacities circuit is similar to the inductive circuit, as reactive power is exchanged between the capacities element and the power source. The only difference is a half-cycle time shift⏳. When the inductive circuit absorbs energy from the power source for half a cycle, it coincides with the capacitor discharging🔄, while in the other half cycle, the inductive element returns energy to the power source, and the capacities circuit charges🔋. By paralleling the capacitor with the inductance, the capacities element can replace the power source in exchanging this part of the reactive power🔗. AC power is necessary to provide active power⚡️, and it's actually quite challenging to achieve complete reactive power compensation. 📌 𝙉𝙤𝙩𝙚: The equivalent circuit of most electrical equipment can be seen as a series circuit of resistor R and inductance L. 𝗪𝗵𝗮𝘁 𝗮𝗿𝗲 𝘁𝗵𝗲 𝗖𝗼𝗺𝗺𝗼𝗻 𝗠𝗲𝘁𝗵𝗼𝗱𝘀 𝗼𝗳 𝗥𝗲𝗮𝗰𝘁𝗶𝘃𝗲 𝗣𝗼𝘄𝗲𝗿 𝗖𝗼𝗺𝗽𝗲𝗻𝘀𝗮𝘁𝗶𝗼𝗻 𝗶𝗻 𝘁𝗵𝗲 𝗣𝗼𝘄𝗲𝗿 𝗚𝗿𝗶𝗱?💡 Common methods of reactive power compensation in the power grid include centralized compensation, distributed local compensation, and single-machine local compensation. ▪  𝘾𝙚𝙣𝙩𝙧𝙖𝙡𝙞𝙯𝙚𝙙 𝘾𝙤𝙢𝙥𝙚𝙣𝙨𝙖𝙩𝙞𝙤𝙣📍  Connecting the compensating capacitor directly to the high or low voltage bus-bar of the substation to compensate for the reactive power within the power supply range of the substation is known as centralized compensation. Capacitors are centrally installed on the 6-10 KV bus-bar of the enterprise or regional main step-down substation to improve the power factor of the entire substation, making the reactive power within the substation's power supply range basically balanced⚖️. This can reduce reactive power loss in high-voltage lines and improve the power supply voltage quality of the substation📈. ▪ 𝘿𝙞𝙨𝙩𝙧𝙞𝙗𝙪𝙩𝙚𝙙 𝙇𝙤𝙘𝙖𝙡 𝘾𝙤𝙢𝙥𝙚𝙣𝙨𝙖𝙩𝙞𝙤𝙣🔧  Connecting the capacitors to the bus-bar of the workshop power box to compensate for the reactive load of nearby motors is known as distributed local compensation, compared to centralized compensation in the main distribution room. This method is suitable for high-voltage distribution devices or low-voltage power devices near distribution boxes with a relatively dense group of motors🔋. It is particularly suitable for motor groups of 4 KW or less in low voltage or backup high-voltage motor groups. ▪ 𝙎𝙞𝙣𝙜𝙡𝙚-𝙈𝙖𝙘𝙝𝙞𝙣𝙚 𝙇𝙤𝙘𝙖𝙡 𝘾𝙤𝙢𝙥𝙚𝙣𝙨𝙖𝙩𝙞𝙤𝙣🛠  Placing the capacitors near the motor for individual local compensation is called single-machine local compensation. This method is mainly suitable for motors that operate for long hours annually⏲️. #PowerGrid #Electrician #ReactivePowerCompensation #Capacitor #Inductor #PowerSource #ElectricalEquipment #Motor #PowerFactor #ElectricalNetwork

Learning no 1; 💠Real power (active power) flows from generators to loads in an electrical system, performing useful work. 💠Reactive power supports voltage levels and flows from higher voltage areas to lower voltage areas. 💠Power angle differences impact power flow in AC systems but are not limited to a specific 23-degree threshold. 💠Series compensation involves adding capacitors to transmission lines to enhance power transfer capacity. 💠Power factor correction is achieved by adding capacitors to improve system efficiency and reduce grid burden. 💠Reactive power compensation combines inductors and capacitors (shunt compensation) to maintain voltage levels and reduce losses. 💠Power system dynamics are influenced by a range of factors, including impedance, load, and network conditions. 💠In practice, power flow control and voltage management are complex tasks, considering system stability and reliability. 💠Transmission upgrades or grid reconfigurations may be needed to address power flow constraints. 💠The specific approach to power flow control and compensation measures depends on the unique requirements of each electrical system. #powerprojects #powergeneration #powertransmission #powergrid #transmission #powersystems #electricalengineering #electrical #energy #oilandgasindustry #renewables #renewableenergy #engineeringdesign #electricaldesign #oilandgas #electricalmaintenance #oilandgasindustry #transformers

Generator Parameters that affect its performance. In electrical power systems, generators play an important role, Generators convert mechanical energy into electrical energy. Different specifications describe the performance and characteristics. 1-Rated Power (MVA or MW): The maximum power that the generator can deliver continuously without exceeding its thermal limits. 2-Rated Voltage (kV): Voltage at which the generator is designed to operate under normal conditions. 3-Rated Current (A): The current that flows through the generator at its rated power and voltage. 4-Frequency (Hz): The frequency of the generated electrical output, which is typically 50 Hz or 60 Hz in most power systems. 5-Power Factor (PF): It indicates how effectively the generator converts mechanical power to useful electrical power. 6-Efficiency (%): The efficiency of the generator indicates the ratio of useful output power to input mechanical power. It is a measure of how well the generator converts mechanical energy into electrical energy. 7-Short-Circuit Ratio (SCR): Also known as the sub-transient reactance ratio, SCR indicates how well the generator can handle short-circuit conditions. It's a measure of the generator's ability to deliver current during a fault without excessive voltage drop. 8-Voltage Regulation (%): This parameter indicates how well the generator can maintain its output voltage within a certain range when subjected to changes in load or other operating conditions. 9-Synchronous Reactance (Xd): Synchronous reactance is a measure of the internal impedance of the generator. It affects the generator's voltage response to changes in load and fault conditions. 10-Transient Reactance (X'd): Transient reactance represents the initial response of the generator's impedance to changes in load conditions and short-circuits faults. 11-Subtransient Reactance (X''d): Sub-transient reactance is an even faster-reacting component of the generator's impedance, important during the earliest moments of a fault. 12-Inertia Constant (H): The inertia constant represents the generator's ability to maintain its rotational speed during sudden changes in load. Generators with higher inertia constants are more stable in response to disturbances. #generators #power #parameters

How do Emergency shutdown devices contribute to enhancing the safety of photovoltaic (PV) systems during faults? Emergency shutdown systems function by identifying critical conditions within a system and then triggering activation to mitigate potential leaks, explosions, or other significant malfunctions. In PV plants, emergency shutdowns can be accomplished at the inverter level, permitting access to inverters or the inverter pad only when safe conditions are ensured and no noticeable safety hazards exist at the equipment. However, some inverters lack an emergency push button. In such cases, a switch disconnector should be attached to or placed near the inverters. When dealing with these situations, refrain from opening switches labeled "do not disconnect under load" until the load break switch disconnector has been opened and the current flow halted. It is safer to operate the AC switch or breaker before the DC switch disconnector, Do you know why ?! At the PV module and string level, isolation should not be attempted during emergency situations until initial measures have been taken to shut off power or interrupt fault current flow via the inverter and isolating switch. This is because PV connectors are non-load break devices, and thus, current checks should always be conducted first before opening the connectors.

ergy devices. It can either reverse the DC power of the battery into AC power, which can be delivered to the grid or used by AC loads, or rectify the AC power of the grid into DC power, which can be used to charge the battery. Energy storage converter (PCS) consists of power, control, protection, monitoring and other hardware and software electrical components. Divided into single-phase and three-phase cameras, single-phase PCS usually consists of bidirectional DC-DC voltage lifting device and DC/AC AC/DC converter, the DC side is usually 48Vdc, AC side 220Vac. three-phase cameras are divided into two kinds, small power three-phase PCS by bidirectional DC-DC voltage lifting device and DC/AC AC/DC converter two-level device, high-power three-phase PCS by DC/AC High-power three-phase PCS consists of DC/AC AC/DC converter one-stage device. Energy storage converter is divided into high frequency isolation, industrial frequency isolation and non-isolation, single-phase and small power three-phase PCS below 20kW generally use high frequency isolation, 50kW to 250kW, generally use industrial frequency isolation, more than 500kW generally use non-isolation.
