1. Capacity of Power Plants:
Power station capacity, also known as installed capacity, refers to the total active power that all generator sets in a power plant can continuously output under rated conditions. It is a core indicator that characterizes the scale of power plant construction and power production capacity. The commonly used units of measurement for power plant capacity are kilowatts (kW), Megawatts (MW), or Gigawatts (GW). A large power plant has a large capacity and generates more electricity (kWh).
Determining the type of power station requires consideration of multiple factors, among which the most critical is the load factor. We should determine the capacity of the power station based on its purpose and actual load. The correct selection of the power type of the main device is a key element.
1.1 Factors affecting power plants capacity:
■ Resource Conditions: Thermal power plants are affected by the type, quality, and supply of fuel; Hydropower plants are limited by river flow and reservoir water levels; Wind power plants rely on wind speed and wind energy density; The photovoltaic power plants depends on the local solar radiation level.
■ Load Demand: It is necessary to consider peak load and reserve capacity demand at different time periods (to cope with future load growth), determine the total installed capacity of the power plant according to a redundancy factor of 1.2-1.5, and match the configuration scheme of single set power and quantity.
■ Technology and Economy: Constrained by equipment selection, construction costs, and operational efficiency, a balance needs to be struck between safety and economy.
1.2 Rated power of generator sets under different operating conditions (ISO 8528-1 Standard):
■ Continuous Operating Power (COP): The maximum power output for continuous operation under agreed maintenance conditions, providing uninterrupted power to constant loads with no annual runtime limit. Allows 100% rated load operation continuously without overload capability. Typically used as base-load power or standalone power supply in remote areas.
■ Prime Running Power (PRP): The maximum power output for continuous operation under agreed maintenance conditions, supplying variable loads with no annual runtime limit. Can serve as a primary power source replacing utility grid power. Average load over 24 hours must not exceed 70% of PRP. Allows 10% overload capacity (overload ≤1 hour every 12 hours, cumulative annual overload ≤25 hours). Suitable for remote mining sites, construction sites, peak shaving applications, and main power sources in independent microgrids.
■ Emergency Standby Power (ESP): The maximum power output for supplying variable loads during grid failure under agreed maintenance conditions, with a maximum annual runtime of 200 hours. Long-term operation at this level significantly increases failure rates and reduces lifespan. Average 24-hour load must not exceed 70% of ESP. Commonly used as emergency backup power for buildings, hospitals, and other critical facilities during grid outages.
■ Limited Time Running Power (LTP): The maximum power output for supplying constant or temporary variable loads under agreed maintenance conditions, with a maximum annual runtime of 500 hours. Average load factor over 24 hours may reach 100% of LTP, but long-term variable load operation is not permitted. Typically used as temporary emergency replacement power, such as for large-scale events, disaster relief, seasonal backup, or short-term construction projects.
■ Data Center Power (DCP): Specifically designed for mission-critical and data center backup applications in regions with reliable grid power. Provides unlimited-time power supply for variable or continuous loads following a mains failure. Can operate at 100% rated load, but prolonged parallel operation with the utility grid is not allowed. DCP ratings typically correspond to an overhaul interval of approximately 8,000 hours (compared to 15,000 hours for PRP), trading off some service life for higher sustained output capability.

2. Plant Location and Site Configuration:
■ The location of the plant is the principal determination of the type of plant best configured to meet its needs. On site collection of data on site altitude, temperature and humidity, geological bearing capacity, and distribution of surrounding electricity load; Confirm the supporting conditions for fuel transportation and storage.
■ Other important parameters that govern the selection and location of the power plant are distance from transmission lines, location from fuel ports or fuel pipelines, and type of fuel availability. Site configuration is generally not a constraint. Periodically, sites are encountered where one plant configuration or another is best suited.
3. Installation Forms of Power Plants:
■ Stationary Power Plants, including Factory-style (Frame style) power plants and Containerized power plants.
■ Mobile Power Plants, including vehicle-mounted power plants and trailer mounted power plants.
■ Floating Power Plants, including power barges and offshore platform power plants. We can provide classification society certificates according to user requirements.
4.Configuration Types of Power Plants:
■ Simple Cycle Power Plants (SCPP), It is consist of a single or multiple gas turbine (or I.C.E) driven generator sets.
■ Cogeneration Power Plants, also known as Combined Heat and Power (CHP).
■ Combined Cycle Power Plants (CCPP), refer to the Combined cycle power generation system composed of gas turbines, generators, boilers, steam or heating type steam turbine.
■ Hybrid Power Plant (HPP), refer to a kind of power generation system combining two types of energy, which common form is hybrid power generation combined by renewable energy sources (wind power, hydroelectricity, solar energy, ocean energy, etc.) and fossil power.

5. Design of core system for Power Plants (Taking HFO power plant as an example):
■ Main gensets selection design: Priority should be given to specialized diesel engines suitable for high viscosity HFO, and generator sets selection should match the requirements of ISO 8528 standard. The steady-state voltage regulation rate and frequency fluctuation rate parameters of the sets should be determined according to the operating conditions.
■ Fuel system design: Set up a two-stage storage system consisting of the main fuel oil storage tanks and daily fuel oil tank, equipped with HFO preheating, filtration, and oil-water separation pretreatment units. The pipeline is made of metal material and equipped with heat tracing and insulation devices. Install a safety shut-off valve at the refueling hose according to GB50156 specifications.
■ Layout design of Power house: The foundation of the gensets adopts reinforced concrete structure, with a thickness not less than 1.5 times the total weight of the sets, and maintenance passage of ≥ 1.2 m is reserved. The air inlet and exhaust systems of the machine room are independently set up, and supporting noise reduction, shock absorption, insulation and noise reduction facilities are provided.
■ Electrical system design: Design high/low voltage distribution circuits, configure black start, relay protection, grounding system, and reactive power compensation devices; Design a fully automatic parallel control system for multi sets scenarios to meet the requirements of dynamic load distribution.
■ Design of Environmental Protection Systems: If necessary, it can be equipped with flue gas desulfurization and denitrification, particulate matter capture devices, and oil containing sewage collection and treatment units. The emission indicators meet the requirements of local atmospheric and sewage discharge standards.
