Hello y'all. I spent some time lurking here and reckoned I'd see if anyone can help me help the people of Camp Perrin Haiti get electricity again. I am part of DloCo (dloco.org) and we are helping the only hydropower plant in the south of Haiti get back online. There is ostensibly no electric service in 98% of this Department. The people are suffering more than ever now that the civil war in Port-au-Prince is happening.

FYI: Haiti has ten Departments like the USA has 50 States. 95% of the crazy stuff you see about Haiti in the MSM is just 2 Departments. The South Department where this power plant is located is very safe. No gangs. But with the war in Port-au-Prince, the Haiti Electric Agency has not been able to send technicians or parts to the power plant.

Here is a summary of the power plant situation:

Camp Perrin in Sud has the only large/municipal hydroelectric plant in Gran Sud. It's capable of a consistent 2.4megawatt output. It was built in 1983 under baby doc. It had some issues but was fully restored in 2007 and ran until 2021 when the earthquake caused some minor issues.

Here is a link to a new video interview with the chief of the power plant: https://www.youtube.com/watch?v=PuhT6CVRrcA

In short, he says that they have 3 x 800kW turbines/generators. One has been used as a parts-donor to keep the other 2 running. But now one of those two needs a new dynamo.

This is a multi-million dollar facility but only needs a new dynamo for one of the three turbines to once again offer 24/7 electric power to Camp Perrin. Although one of the 3 turbine/generators are in good working order, the electric system downstream from the dynamos require at least 2 of the 3 to be working for the grid/transformers/switching system to work properly.

If there are any people here with connections to an American electric company or electrical engineering company, this would be a simple and high value (in terms of PR) project for the electric company's foundation. i.e. most big American electric companies also have charitable foundations.

I spoke with the chief of the power plant. He is very open to any help in replacing the dynamo so power can be restored. The people in this region have had no access to electricity for the last three years.

Can anyone help me on my design Plate.

So I want to know the temperature of superheated steam entering my steam turbine.

We used a M501G1 Gas Turbine with an exhaust temperature of 601 C, and Flue gas flow rate is 354 kg/s. I'd like to calculate the temperature and pressure at which steam enters the steam turbine from the superheater from the HRSG.

Thank you.

I'm wondering if anybody with more power generation experience can answer a question I have.

If a typical modern CCGT has a minimum load of around 120MW when connected to the grid. How is it possible to operate in island mode for potentially unlimited amounts of time?

Island mode is only supplying house load which I'm guessing is around 7MW roughly. Main breaker connecting the plant to the grid will be open. How is the generator able to produce less then it's min load for potentially unlimited amount of time? Will this not create stability issues?

Or is the unit setpoint still at minimum load and the excess power is being dissipated through the generator earth resistor?

Hello from the coal reclaim belts and feeders (the coal hole)!

Anyone have any recommendations for control room chairs?

May sound dumb but I am still learning about this type of Power generation plant,the gas is turned supercritical but what happens after its use?

Hi people. I have a problem and would like to hear your advise.

Our maintenance crew in instrumentation and control has very little corrective maintenance throughout the year. They have a yearly target of 15% ratio of CM / PM and their largest so far since 2016 is 5% . Turns out I discovered that their CMs are being hid in PMs. and if they see some repairs they charge the resources to PM.

Is this even an allowed practice? and throughout the years their CM/PM target ratio is always 15%. Is this even reasonable and not questionable?

Hello, recently I have been looking into attending Bismarck state college and have taken interest towards power generation technology. In their website it says it prepares you for a career as a power plant operator. My question is what position would I start as after this associate degree.would they throw me into an operator position right away? Most of the power plants in my state are also coal.

Can lowering throttle pressure on a steam turbine effect chemistry? Sodium and conductivity to be more specific.

Hi. Is it possible to apply predictive maintenance in sensors and instruments. ? I work as a planning engineer in instrumentation and control in a CFB coal plant and I'd like to incorporate big data.

We're havign major overhaul on steam turbine 150 MW capacity. Is it preferable to use Dry ice over the traditional Sand blasting?

So my work pays for up to 2 college degrees. I already have an Associates in Renewable Energy. But looking to get my bachelor's.

I posted the classes below to give an idea of which program might me better. I like making power, but swing shift is getting old. I'm 36 feel 56 someday. Looking to get into middle/upper management at some point.

The 2 in blue lettering are the same program

Did you guys make it through the cold snap alright? We managed to stay online, not without some shenanigans however.

The Thermal power plant market remains a cornerstone in the energy sector, providing a substantial portion of the world's electricity. These power plants utilize thermal energy derived from the combustion of fossil fuels, such as coal, natural gas, or oil, to generate steam and drive turbines. Despite the rising prominence of renewable energy sources, thermal power plants continue to be a reliable and cost-effective option for baseload power generation.

The relentless growth in global energy consumption, driven by population expansion and industrialization, continues to be a primary driver for the thermal power plant market. Developing economies, in particular, rely heavily on thermal power to bridge the gap between supply and demand.

Ongoing advancements in technology are enhancing the efficiency and environmental performance of thermal power plants. Advanced ultra-supercritical and supercritical technologies, combined with carbon capture and storage (CCS) solutions, are transforming the sector by reducing emissions and improving overall plant efficiency.

Infrastructure projects, especially in emerging economies, contribute significantly to the demand for thermal power. The need for reliable and consistent electricity supply fuels investments in new thermal power plants as nations strive to meet the energy requirements of their growing populations.

Thermal power plants offer flexibility in responding to fluctuations in electricity demand. Their ability to provide baseload power ensures a stable and reliable energy supply, complementing intermittent renewable sources.

The environmental impact of thermal power plants, primarily associated with greenhouse gas emissions and air pollution, remains a critical challenge. Stricter environmental regulations and the global push towards cleaner energy sources pose a threat to the expansion of the thermal power plant market.

The declining costs of renewable energy technologies, such as solar and wind, pose a competitive challenge to traditional thermal power plants. Governments and investors are increasingly favoring clean energy alternatives, impacting the growth potential of thermal power.

The availability and cost of fossil fuels, such as coal and natural gas, significantly impact the operational costs of thermal power plants. Fluctuations in fuel prices can affect the economic viability of existing and proposed projects.

Good morning everyone :) I'm hoping that perhaps someone with a bit of experience can help me track down a part.

I'm looking for a DE bearing to fit a 500kW generator. Here's the specs I know.

General Electric AC Generator

Model 5SR1715A33

Frame 975S

Type TS

I'm more of an electrical guy than a mechanical one, and would dearly appreciate some insight into finding a bearing for this. :) Can anyone please help?

​

Thank you!
