摘要： In the field of high voltage direct current (HVDC) power transmission, there is a need for an improved power dissipating converter (30). A power dissipating converter (30) for use with a power converter (10) configured to convert between AC power and DC power, comprises first and second DC terminals (12, 14) for connection to a DC network (20). The power dissipating converter (30) also includes a converter limb (32) that extends between the first and second DC terminals (12, 14) and which includes first and second limb portions (34, 36) that are separated by a ground terminal (38) for connection to ground (40). Each limb portion (34, 36) includes a chain- link converter (44) which is connected in series with a power dissipating resistor (46). Each chain-link converter (44) includes a plurality of series-connected chain-link modules (48), and each chain-link module (48) includes a plurality of switching elements (50) that are connected in parallel with an energy storage device (52) whereby each chain-link module (48) is selectively operable to provide a voltage source and the corresponding chain-link converter (44) is selectively operable to provide a stepped variable voltage source. The power dissipating converter (30) further includes a controller (70) which is programmed to operate the power dissipating converter (30) in first and second modes, the first mode being an inactive mode in which the power dissipating converter (30) is prevented from exchanging current with a DC network (20) connected in-use to the first and second DC terminals (12, 14) and no power from the DC network (20) is dissipated by either power dissipating resistor (46), and the second mode being an active mode in which the power dissipating converter (30) exchanges a discharge current with the DC network (20) and power from the DC network (20) is dissipated by each power dissipating resistor (46). The controller (70), when operating the power dissipating converter (30) in the first inactive mode, is programmed to prevent an exchange of current with the in-use connected DC network (20) by controlling the chain-link modules (48) in each chain-link converter (44) to store an individual energy amount whereby the cumulative voltage source provided by the sum of all of the individual energy amounts in a respective chain-link converter (44) is equal to the DC voltage presented at the corresponding DC terminal (12, 14).

摘要： Disclosed is a beater plate (10) for a dynamic beater wheel (100) in a beater mill assembly (1000) for pulverizing coal. The beater plate (10) includes a layer of hard-faced surface (12). The layer of hard-faced surface (12) is obtained by hardfacing a surface of the beater plate receiving the coal. The beater plate (10) further includes a layer of coating (14) comprising hard particles. The layer of coating (14) is disposed over the layer of hard-faced surface (12). The hard particles of the layer of the coating are uniformly dispersed in the metal matrix of the beater plate (10), and wherein the hard particles are having more than 50wt% of particles of the coating uniformly dispersed in the metal matrix of the plate (10). Also disclosed is a process of making the beater plate (10), and configuration of the beater plate (10) with the dynamic beater wheel (100).
