Wind power plants are an increasingly common source of electricity located in rural areas. As a result of the high variability of wind power, and thus the generated power, these sources should be classified as unstable sources. In this paper, the authors attempted to determine the impact of wind turbine operation on the parameters of electricity supplied to farms located near the source. As a result of the conducted field tests, variability courses of the basic parameters describing the supply voltage were obtained. The influence of power plant variability on the values of voltage, frequency, and voltage distortion factor was determined. To estimate the capacity of the transmission lines, the reactive power produced in the power plant and its effect on the value of the power factor were determined. The conducted research and analysis showed that the wind power plant significantly influences voltage fluctuations in its immediate vicinity (the maximum value registered was close to 2%, while the value required by law was 2.5%). Although all the recorded values are within limits specified by the current regulations (e.g., the THD value is four times lower than the required value), wind turbines may cause incorrect operation of loads connected nearby. This applies mainly to cases where consumers sensitive to voltage fluctuations are installed in the direct vicinity of the power plant.

Abstract In Gas turbine-based combined cycle power plant market, the customer conducts an economic evaluation of competitive products to decide their buying option. There are different methods to calculate the economics of a power plant like Levelized cost of electricity (LCOE), Net present value (NPV) and payback period. LCOE methodology is commonly used for lifecycle cost analyses for combine cycle power plant that covers cost details of the plant and plant performance over the complete lifetime of a power plant from construction to retiring. Typically, it includes a combine cycle power plant ownership costs (Total plant cost and operating & maintenance cost) and combine cycle power output and efficiency. This LCOE method is helpful to compare power generation system that use similar technologies. This paper encompasses the LCOE calculation method, assumptions & approach to analyze the impact of key parameters of the electrical generation cost. They key parameters includes combine cycle output, combine cycle efficiency, fuel cost, annual operating hours, capital charge factor, annual operating hours, power plant life, discount rate, nominal escalation rate, operating & maintenance cost. This paper analyses result will provide insights to the customer & Gas turbine-based OEM (Own Equipment Manufacturing) companies to focus on different area/parameters to reduce the unit cost of generating electricity.

The paper presents studies on the impact of the process of condensation of water vapour on the process of cleaning of flue gases from acidic compounds. The measurements were carried out on a pilot-scale plant for waste heat recovery from flue gases, taking into account the process of condensation of the water vapour contained in them. The plant was connected to a lignite-fired power unit with a capacity of 360 MW located at PGE GiEK S.A., Bełchatów Power Plant Branch. The impact of the condensation of water vapour on the reduction of sulphur, chlorine and fluorine forming acidic compounds was examined. The studies show that the condensation process is conducive to removal of acidic compounds from flue gases.

Currently, many coal-fired powers plants are built to supply electrical energy needs in Indonesia due to relatively inexpensive raw materials and abundant in Indonesia. Handling of coal is mostly done at the power plant using coal handling facilities consisting of ship unloaders, conveyor belts, stock piles, silos or bunkers. The problem that arises in the coal handling facility is dust from coal that fells or hovers in the air so that it can interfere with the environment and health both for workers in the Coal Power and residents around the Coal Power. The purpose of writing this paper is to eliminate the spread of coal dust that arises due to coal handling equipment that is not precise and imperfect. The method used is the Soft System Methodology (SSM), which is a systematic approach used to analyze and solve problems in complex and messy situations. This paper examines the benefits of applying SSM to knowledge management issues in handling coal dust at a power plant. Improvement is done by upgrading coal handling equipment (ship unloader, conveyor belt, stock pile) with the addition of dust suppression, proper sealing system, dust bag, and training to operators on the impact and handling of coal dust and coal handling equipment maintenance, so resulting in a significant decrease in the spread of coal dust, creating a working environment and the environment becomes clean, healthy and safe.

Abstract With the development of the nuclear energy industry and the increasing demand for environmental protection, the impact of nuclear power plant radiation on the environment has gradually entered the public view. This article combs the nuclear power plant radiation environmental management systems of several countries, takes the domestic and foreign management of radioactive effluent discharge from nuclear power plants as a starting point, analyses and compares the laws and standards related to radioactive effluents from nuclear power plants in France, the United States, China, and South Korea. In this paper, the management improvement of radioactive effluent discharge system of Chinese nuclear power plants has been discussed.

Healthy fish populations are critical to healthy ecosystems: they feed communities, support economies and are essential to our survival. But our oceans are facing growing threats and greater uncertainty. Overfishing, climate change, habitat destruction and pollution are degrading the underwater world and putting the marine life we all depend upon at risk. Much is at stake, as the status quo is demonstrably not working. The number of stocks in the healthy zone has decreased since Oceana Canada released its 2018 Fishery Audit, and the number in the critical zone has increased — including crab and shrimp stocks. This isparticularly worrying if the depletion of crustaceans becomes a trend, as the value of Canada’s seafood industry depends heavily on them. Progress on implementing rebuilding plans remains slow and many critically depleted stocks, including northern cod, are still without a plan. As well, Fisheries and Oceans Canada (DFO) has not yet indicated how and by when it will collect adequate catch monitoring information, needed to measure and manage bycatch (the incidental catch of non-target fish) in all Canadian commercial fisheries. Meanwhile, only two of the 11 recommendations from the 2018 Fishery Audit have been implemented. DFO has made some progress since the last Fishery Audit was released. In 2019, DFO published more information to help assess fish stock health, and some elements of fishery monitoring became more transparent. DFO also implemented some of the recommendations from the 2016 Auditor General report on sustainable fisheries, including developing timelines and priorities for rebuilding plans for depleted fish populations. Most importantly, a modernized Fisheries Act became law in June 2019. For the first time in the Act’s history, rebuilding plans are now required for depleted fish populations. The government has committed more than $100 million over five years to assess and rebuild fish stocks. This brings Canada into the group of nations with modern fisheries laws and could signal a historic turning point in the health of Canadian fisheries. The impact of the new Act will depend on the strength and pace of regulations, currently under development. The regulations will outline what rebuilding plans must include, and Oceana Canada is advocating that, at a minimum, they should specify a timeline and target, aimed at rebuilding stocks to healthy levels. In the year ahead, the federal government must develop strong and effective regulations to support the rebuilding provisions in the Fisheries Act and accelerate the implementation and enforcement of existing policies. Fortunately, there is a strong base of support for new regulations to rebuild stocks, new funding commitments and much-needed increases in DFO’s science capacity to get the job done. We have the tools needed to modernize Canada’s approach to fisheries management and rebuild fish populations, and Canadians want to see this happen. In a recent Abacus Data market research survey, 98 per cent of Canadians said it was important that the federal government work to rebuild abundant fish populations. If the government fails to take these actions, we can expect the number of healthy stocks to continue to decline and depleted populations will fail to recover, impoverishing the oceans and the coastal communities who depend on them.
