Government-owned Corporation
A state-owned enterprise (SOE) is a government entity which is established or nationalised by the ''national government'' or ''provincial government'' by an executive order or an act of legislation in order to earn profit for the government, control monopoly of the private sector entities, provide products and services to citizens at a lower price and for the achievement of overall financial goals & developmental objectives in a particular country. The national government or provincial government has majority ownership over these ''state owned enterprises''. These ''state owned enterprises'' are also known as public sector undertakings in some countries. Defining characteristics of SOEs are their distinct legal form and possession of financial goals & developmental objectives (e.g., a state railway company may aim to make transportation more accessible and earn profit for the government), SOEs are government entities established to pursue financial objectives and deve ...

Tungabhadra Dam
The Tungabhadra Dam, also known as Pampa Sagar, is a water reservoir constructed across the Tungabhadra River in the city of Hosapete Bellary district, Karnataka, India. It is a multipurpose dam serving irrigation, electricity generation, flood control, ''etc''. for the state. It is one of the only two non-cement dams in India, the other being the Mullaperiyar Dam in Kerala. The dam is built of ''surki'' mortar, a combination of mud and limestone, commonly used at the time of its construction. The dam was a joint project undertaken in 1949 by the erstwhile Kingdom of Hyderabad and Madras Presidency when the construction began; later, after India's constitution into a republic in 1950, it became a joint project between the governments of Mysore State (now Karnataka) and Hyderabad State (now Telangana). The construction was completed in 1953. The Tungabhadra Dam has withstood the test of time for over 70 years and is expected to well cross many more decades. The chief archit ...

Power Sector Of Andhra Pradesh
Power sector of Andhra Pradesh is divided into 4 categories namely ''Regulation'', ''Generation'', ''Transmission'' and ''Distribution''. ''Andhra Pradesh Electricity Regulatory Commission (APERC)'' is the regulatory body. '' APGENCO'' deals with the electricity production and also maintenance, proposes new projects and upgrades existing ones as well. The APGENCO also set up a Special Purpose Vehicle (SPV), named as ''Andhra Pradesh Power Development Company Limited (APPDCL)'', a joint venture company of APGENCO (with 50% equity) and IL&FS (50% equity) to set up Krishnapatanam thermal power project (2x800 MW). '' APTRANSCO'' is set up for transmission of power. Power distribution in the state is divided into three divisions, namely ''Eastern Power Distribution Corporation Limited'' (APEPDCL), ''Central Power Distribution Corporation Limited'' (APCPDCL) and ''Southern Power Distribution Corporation Limited'' (APSPDCL), which distributes the power to the households, agriculture and ...

List Of Hydroelectric Power Station Failures
This is a list of major hydroelectric power station failures due to damage to a hydroelectric power station or its connections. Every generating station trips from time to time due to minor defects and can usually be restarted when the defect has been remedied. Various protections are built into the stations to cause shutdown before major damage is caused. Some hydroelectric power station failures may go beyond the immediate loss of generation capacity, including destruction of the turbine itself, reservoir breach and significant destruction of national grid infrastructure downstream. These can take years to remedy in some cases. Where a generating station is large compared to the connected grid capacity, any failure can cause extensive disruption within the network. A serious failure in a proportionally large hydroelectric generating station or its associated transmission line will remove a large block of power from the grid that may lead to widespread disturbances.

Availability
In reliability engineering, the term availability has the following meanings: * The degree to which a system, subsystem or equipment is in a specified operable and committable state at the start of a mission, when the mission is called for at an unknown, ''i.e.'' a random, time. * The probability that an item will operate satisfactorily at a given point in time when used under stated conditions in an ideal support environment. Normally high availability systems might be specified as 99.98%, 99.999% or 99.9996%. Representation The simplest representation of availability (''A'') is a ratio of the expected value of the uptime of a system to the aggregate of the expected values of up and down time (that results in the "total amont of time" ''C'' of the observation window) : A = \frac = \frac Another equation for availability (''A'') is a ratio of the Mean Time To Failure (MTTF) and Mean Time To Repair (MTTR), or : A = \frac = \frac If we define the status function X(t) as : X ...

Load Following Power Plant
A load-following power plant, regarded as producing mid-merit or mid-priced electricity, is a power plant that adjusts its power output as demand for electricity fluctuates throughout the day. Load-following plants are typically in between base load and peaking power plants in efficiency, speed of start-up and shut-down, construction cost, cost of electricity and capacity factor. Base load and peaking power plants Base load power plants are dispatchable plants that tend to operate at maximum output. They generally shut down or reduce power only to perform maintenance or repair or due to grid constraints. Power plants operated mostly in this way include coal, fuel oil, nuclear, geothermal, run-of-the-river hydroelectric, biomass and combined cycle natural gas plants. Peaking power plants operate only during times of peak demand. In countries with widespread air conditioning, demand peaks around the middle of the afternoon, so a typical peaking power plant may start up a couple ...

Thermal Efficiency
In thermodynamics, the thermal efficiency (\eta_) is a dimensionless performance measure of a device that uses thermal energy, such as an internal combustion engine, steam turbine, steam engine, boiler, furnace, refrigerator, ACs etc. For a heat engine, thermal efficiency is the ratio of the net work output to the heat input; in the case of a heat pump, thermal efficiency (known as the ''coefficient of performance'') is the ratio of net heat output (for heating), or the net heat removed (for cooling) to the energy input (external work). The efficiency of a heat engine is fractional as the output is always less than the input while the COP of a heat pump is more than 1. These values are further restricted by the Carnot theorem. Overview In general, energy conversion efficiency is the ratio between the useful output of a device and the input, in energy terms. For thermal efficiency, the input, Q_, to the device is heat, or the heat-content of a fuel that is consumed. The de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
